Monday with Saint Paul


Dr Abe V Rotor
 



One Monday I visited Saint Paul with inquiries I never asked before;
Fifteen years I served him, a teacher of this school, keeper of a museum;
Time has changed the world, global is its effect, would St Paul tell me
More of the ways of the world to give life a meaning? So I assumed  

"Tell me where Damascus Road is where you heard God speak;
Tell me how you crossed the Mediteranean in a storm and survived; 
Tell me how you carried the Word amongst unbelievers and Pharisees;
Tell me how you faced death yet keep alive your faith and noble pride.

"Tell me where have the Gentiles you converted and followers gone;
Tell me how you wrote the scriptures that gave the bible a wider view;
Tell me how man can become a saint and a saint to become man; 
Tell me how to reach heaven without striving to be a martyr like you."  

The sun rose high, sending reflection of gray clouds on giant glass panes; 
The pavement is bare, the marble floor a mirage, yet empty as the sea;
High rise the buildings are - towers and spires, proud symbols of power;
In the deep silence: I heard the same words, "Why do you persecute me."  ~

Rock Pool - Miniature Copy of the Sea


Dr Abe V Rotor
Rock Pool by the Sea I, in acrylic by the author 

How can the sea, so deep and vast leave behind an offsping
between two worlds? 
Wonder if Nature is kind, abiding to the laws and values 
of Man as her guardian.
If there was any mistake in God's creation after His rest
on the seventh day.
If perfection is but a long time goal beyond man's time
and imagination. 
  
Rock Pool by the Sea II, in acrylic by the author

Wonder if creation is a long and painful process called evolution
 in the book of sages;
And change is a continuing process on a crossroad of possibilities,
 chartless and endless;  
Yet in every second or in man's life time, creation goes on and on 
beyond understanding;
And soon the rock pool becomes a sea in itself, a miniature copy
of its magnificence.     


 

The Happy Expressions of Home

Dr Abe V Rotor
Living with Nature - School on Blog
Paaralang Bayan sa Himpapawid with Ms Melly Tenorio
738 DZRB 8 to 9 evening class, Monday to Friday

Lesson: Home has as many expressions as people's thoughts and feelings about it. Let's take a glance on what they say.
 Top: Bahay Kubo in oil by AVR patterned after the song of the same title; 
Lower photos: western bungalow cottage; typical bamboo and nipa house.   
Light through the kapis window brings in warmth and nostalgia in this old home.


1. For a home beauty and function are one, in the same way as in biology – morphology and physiology.

2. Aesthetics is an art – it is both natural and man-made; it is a harmonious combination of the two.

3. Sanctuary is a home, simulated from the natural habitat of an organism or group of organisms. Sanctuary implies values of kindness, care, respect and understanding.

4. Generally, there are two parts of our garden to landscape – the public area and the private area, which are self explanatory.

5. Home is a call, ancient craving, in fact, biological like the salmon and the dove. It is the same homing instinct of the balikbayan.

6. Home is a fortress and a lighthouse.

7. Home is made by man and perfected by his hopes and dreams. We can reach the state of perfection, if only we do the best we can.

8. These are great Filipino artists whose works contributed to having our happy home of today: Nicanor Abelardo (music), Fernando Amorsolo (painting).



Home is a workshop. It is a place to discover and develop talents.

9. These are great Filipino scientists whose works are worthy as well in building an integrated home: Nemesio Mendiola (agriculture/gardening); Deogracias Villadolid (freshwater fishery), Leon Ma Guerrero (medicinal plants), Angel Arguelles (organic farming).

10. Other great Filipino women whose works likewise contributed to the making of a happy home: Fe del Mundo (health, specially children’s healthcare),  Maria Y Orosa (home economics/food art).

11. Even how inadequate may be our home – even if it is located along the railway - it comes to full bloom when Christmas time comes.

12. A home is a movable feast, referring to Ernest Hemingway’s early novel The Movable Feast.


Home is a greenery

13. A home must be efficient in protecting the dwellers from ultraviolet rays that causes skin cancer, unburnt carbon and acid rain that cause allergy and other ailments.

14. A home is surrounded by trees. Trees buffer disturbing noise from traffic, but they are good resonators of music and conversation.

15. A 20-year old acacia tree gives a cooling effect in its shade the equivalence of 10-window type air conditioner 24 hours a day, 365 days a year, virtually without any cost.

16. Have plants in and around your home. Plants give off O2 as a by-product of photosynthesis. It is good to health.

17. The best model for a garden is the Filipino style, because it is patterned after the structure of a tropical rain forest.

18. A home garden simulates a tropical rain forest which is basically made up of four stories just like a tall building: ground plants, shrubs, bushes and small trees, canopy layer, and emergents.

19. The most common canopy trees are most fruit trees, like santol, avocado, mango, while the most common emergent is the coconut.

20. A home is compared to a bird's nest. After the chicks have grown up and have learned to fly, they leave the nest. The difference from that of the bird's nest is that, the home is not abandoned. Now and then. the children visit their parents (and grandparents).

21. Life and love emanate, reside and grow in the home.

22. Home is “heaven on earth.”

23. Home is a rocking chair with long arms.

24. Home can be missed sorely like Heidi in Sipyri’s novel, about an orphan girl who was separated from her grandfather in the Alps mountain. Only when she was able to go back to her home with his grandfather that she found her world complete gain.

25. A broken home is the most difficult to bear – broken by divorce, misunderstanding, quarrel, by early death, by prolonged absence – and most especially, by apparent lovelessness. If you belong to this kind of home there are two things you can do. Rebuild it, pick up the pieces and mend them together. The other is to make a new home yourself, and make it the ideal home of your dreams, the ideal home which is the highest expression of our worthiness on earth, and worthiness in heaven. ~

Mandala (haystack) – engineering feat of old folks


 7 Principles that make the mandala a wonder of the world 
Dr Abe V Rotor 

 Mandala, typical in the Ilocos Region and Central Luzon, and other parts of the country.  The mandala is associated with idyllic life, a respite on the part of the farmer, a time to fly kites for children, vacation time in the province.  The mandala is a symbol of prosperity and security. Painting by the author, details of a mural c. 2002 

The mandala is indeed an engineering feat, especially the tall ones.  Without any structural reinforcement except a single bamboo post at the center, this giant mushroom-like heap of rice hay can grow very high, up to twelve feet, although farmers today prefer to build smaller mandala but in groups. It is mainly because the varieties planted now are shorter than the native varieties that are now rare. Here are some amazing features of the mandala.
  1. When it rains the haystack gets wet only on the outside (animal fur principle).
  2. There is natural ventilation inside the stack preventing growth of fungi and bacteria, and the buildup of heat.
  3. Aerodynamics kept the structure in shape, whatever is the strength and direction of wind. 
  4. The haystack supplies domestic animals their regular supply of roughage, until the next harvest comes. As the lower part of the stack is consumed by the animal the whole weight slowly comes down to replenish it.
  5. The remaining hay is used as mulch for vegetables and seedlings. It is also used as mushroom bed, temporary roofing and shed, and material for making compost.
  6. It is often a practice to stock palay-on-the-stalk (unthreshed) mandala style, a practical way of storage, where there are no poachers and rodents. 
  7. The mandala is a associated with village festivities. Our national artist, Fernando Amorsolo painted immortal scenes around the mandala.
Next time you travel to the countryside find time to visit the mandala.  Take time to examine its structure. Ask the builders their secrets - the seven principles that make the mandala a wonder of the world. 
   
 Haystacks fascinated Vincent van Gogh.  He made several painting of the same subject. Here are three versions.  Upper photo shows a twisted haystack apparently moved out of its center of gravity.  It's Van Gogh's characteristic style, like his Starry Night. The second version (left) shows well-balanced haystacks with perfect cone.  The third focuses more on idyllic life beside a haystack, as if it give comfort and warmth to tired souls.

Golden Homesite Plan of Ed Nankil


Dr Abe V Rotor

Golden Homesite Plan was submitted by Mr Ed Nankil to Paaralang Bayan sa Himpapawid (people's School on Air) as an assignment.  Its vivid presentation touches six (6) interrelated lessons, namely:
 
1. Homesite 1000 sq m area or equivalent to 1 mu, average farm size in China extensively cultivated to sustain more than the needs of the family, but for the market as well. Recommended particularly for those preparing to retire, and retirees, thus the name - Golden Homesite. 


2. Integration - horizontal (crops by season spread year round), and vertical (multi-storey cropping, thus a 1000 sq m area is equivalent to 2000 up to 5000 sq m effective area, depending on the "layers" of crops raised at a given time. Depends greatly on multiple cropping and crop rotation technology, and non-cash inputs.  Tri-commodity approach (crops, animals and fish) .

3. Self-sufficiency target in food of farm products (fruits, vegetables, fish, poultry and livestock), as well as garden products (flowers and herbals). Model applies to both urban and rural setting. 




4. Agro-ecology - unity and harmony of farming and environmental conservation,  underlying principle of sustainable productivity. Include recycling (composting), natural farming (least use of chemical-based input, and non-GMO plants and animals), optimum, instead of maximum utilization of the land, thus allowing it to fallow or rest.  

5. Bahay Kubo concept functionally modified to meet present conditions. Reliance on local resources (bamboo, nipa, coco lumber), homesite and house design (trees as windbreak and shade, pond cools the surroundings, natural ventilation).  Homesite is also a wildlife sanctuary, helps restore threatened and endangered species of plants, birds, others. 

6. Strengthen family bond, restrains migration to the city, upholds Filipino dignity and promotes indigenous culture. The homesite provides a healthy environment for growing up and for spending the golden years of life, it is a workshop, a place to learn, enjoy, reflect and meditate.   

The above lessons are invariably discussed in this blog (LIVING WITH NATURE) from among 3000 posts.  Acknowledgement: Mr Ed Nankil.  More power to you!


Garlic: Miracle Health Food and Medicine


Dr Abe V Rotor
 Living with Nature School on Blog
Paaralang Bayan sa Himpapawid with My Melly C Tenorio
738 DZRB AM Band 8 to 9 evening class, Monday to Friday 
There's a universal belief that garlic drives evil spirits away. Well, 
this time it's insect pest that it will drive out of your garden.

      Basang, auntie and yaya of the author, used to treat kabag (gas pain) with garlic.  She would roast two large cloves over candle, crush and wrap them with a piece of cloth, and while still warm, apply the bandage around both large toes.  She made sure that the garlic covers the joint at the base of the nail. While doing it she inaudibly said some prayer imploring divine intervention. And indeed, relief would come in an hour or less.

     “The garlic draws out the gas,” she explained. “But before the trapped gas is released, garlic relieves tired and cold nerves, frees cramped muscles, drives out tension, and restores normal body temperature.” This is what people call traditional medicine - or natural medicine, as some put it. Today, the term natural is more than just the use of herbals known to be effective, but also includes the enhancement of normal healing without the side effects of synthetic drugs.

     Many years later when the author suggested to his family doctor to apply the same remedy to his own children.  The family doctor just smiled and scratched out a prescription, which the patient was to take every after meal. Meantime to relieve the pain, he gave Carlo, the author’s youngest son a tablet, which soon made him comfortable. The author may have known the brand and generic names of the medicine but how it worked was not explained as vivid as Basang described the roasted garlic wound around the large toe. Oh well, that is the difference between traditional and modern medicine.

     Since the advent of modern medicine, the medicinal value of garlic has been virtually forgotten, and this once powerful panacea has been relegated to the kitchen. The fact is that garlic is the oldest recorded herbal remedy to a long list of human afflictions, dating as far back to the ancient Chinese and Egyptian civilizations.

Ancient Healing with Garlic
     We do not know when garlic was first used as food or medicine, but in a book, Calendar of Hsia, written 4000 years ago, it tells us how the followers of Emperor Huang-ti who happened to have eaten a poisonous plant were saved by eating wild garlic they called suan. Since then garlic became an important Chinese herbal medicine.

     Garlic bulbs were found in the tomb of the celebrated Egyptian king, Tutankhamen, an evidence of the inscriptions of earlier pyramids describing garlic as food and medicine.  The Israelite slaves who built the pyramids drew their strength and nourishment from garlic. And the bible mentioned how Moses and the Israelites sorely missed it while they were crossing the desert after fleeing Egypt.  Garlic as food and medicine is also mentioned in the Koran, in the writings of the Babylonians, Greeks and Romans. The Vikings took garlic among their provisions in long sea voyages. 

       In the Middle Ages, Jewish superstition suggested that carrying garlic bulbs would protect a person from the dreaded pestilence, the Bubonic plague, which decimated the population of medieval Europe by more than one-third. The scientific explanation of course, is that garlic has antiseptic and anti-microbial properties against the bacterial pathogen, while its volatile oil repels the flea vector (Xenopsylla cheopis).  But during those times the magic of garlic was ascribed to superstition that it drives evil spirits, a belief many still hold today.  In the provinces we still see garlic hanging at the doorway and around the house for fear of  aswang and manananggal, monsters of the evil world who scare and even hurt people.

Origin of Herbolarios

   Don’t you know that the great Greek doctor, Hippocrates, applied garlic on a variety of diseases, including leprosy? Hippocrates, the “father of medicine” and author of the Hippocratic Oath, code of ethics in the medical profession, made garlic popular as treatment for wounds and toothaches, and as diuretic and laxative.

     When the Romans conquered the Greeks, many of the medicinal practices such as the use of garlic were continued.  The Roman doctor Dioscorides spoke highly of garlic.  To wit:

“It is sharp, biting, wind-producing, and excites the belly, dries out the stomach, creates thirst and reduces growths on the skin.  If eaten it helps eliminate tapeworm, it drives out urine.  It is good against snakebite with wine or when crushed in wine.  It is good against the bite of a rabid dog. It makes the voice clear and soothes continuous coughing when eaten raw or boiled.  Boiled with oregano, it kills lice and bed bugs. It doth clear the arteries.  Burnt and mixed with honey, it heals white skin spots, herpetic eruptions, liver spots, leprosy and scurvy.  Boiled with pinewood and incense, it soothes toothache when the solution is kept in the mouth. Boiled flowers are good for bath to help the coming of menstruation.  x x x” 

     Why these are the very things our local herbolarios are practicing! Could it be that natural medicine spontaneously developed along with the evolution of man and his society? A subject that deals with the natural relationship between man and plants – ethonobotany – is offered at the Graduate School of the University of Santo Tomas. 

Phytochemicals of Garlic

     What secrets really has garlic for being a powerful medicine?  Paul Simons in his book, Garlic, the Powerful Panacea, did an extensive research on the phytochemical properties of garlic. These are: 

1. Allicin - This substance is believed to be largely responsible for giving garlic its anti-bacterial and anti-inflammatory effect.

2. Alliin - Garlic is often known as Russian Penicillin and the Russians believe, as do many other scientists, that this is the substance that produces its antibiotic activity.

3. Di-sulphides - These are believed to have a cholesterol lowering effect, which help control cholesterol and other fats within the arteries and blood vessels.

4. Anti-haemolytic Factor - It is claimed that this is responsible for the beneficial effect of garlic in the treatment of anemia.

5. Anti-arthritic Factor - Japanese research teams investigating arthritis and similar conditions claim this factor to be present in garlic.

6. Sugar Regulating Factor - It was reported in 1973 that garlic is useful for treating some forms of diabetes. It is this factor that is believed to be the cure.

7. Anti-oxidant Factor - Garlic has been shown capable of helping prevent foods from going rancid and spoiled. Garlic is a natural food preservative.

8. Anti-coagulant Factor - Garlic contains certain active substances which prevent blood from coagulating, thus benefiting heart conditions.

9. Allithiamin - This special type of vitamin B1 has been isolated from garlic and has beneficial properties as defense against infection.

Garlic as an Aphrodisiac

     In Philippine Herbs to Increase Sexual Vitality (1999), a book written by Dr. Romualdo del Rosario, Dr. Delia Ontengco and the author, garlic was described as a powerful aphrodisiac. Its use as an aphrodisiac is widespread among Egyptians, Greeks, Romans, Chinese, Japanese, Swedish and Germans.  The East German pharmaceutical journal Die Pharmazie says that garlic is especially suited for men and women of climacteric age because it contains compounds related to sex hormones. 

     The aphrodisiac effect is also associated with the fact that it makes food more appetizing, stimulates secretion of gastric juices, increases the appetite, tones up the organs, builds stamina and strength, and generally contributes to a feeling of well-being.

Garlic -  “White Gold”

      From the economic point of view, garlic is regarded as a high-value crop with farmers earning as much as three times more than rice or corn. Generally, garlic is planted soon after the rice crop is harvested in November or early December. It is harvested before summer sets in.  The two Ilocos provinces comprise the garlic capital of the Philippines, contributing up to eighty percent of national production which is equivalent to 15,000 metric tons, well worth above P100 million a year.  However, with the present globalization policy, imported garlic mainly from China, is threatening the local garlic industry.   Imported garlic is very much larger in size and cheaper, although our own is more pungent and aromatic.

Nutritional Composition of Garlic

     What nutrients do we get from garlic?  According to the US Department of Agriculture, raw garlic gives 31 percent carbohydrate, 6 percent protein and 0.2 percent fat.  It contains 61 percent water.

     As to minerals, a 100-gram dried sample has the following mineral contents:
·         Calcium - 29 mg,
·         Phosphorus - 202 mg,
·         Iron - 0.5 mg, and
·         Potassium - 529 mg.

     Calcium is important for our bones, while Phosphorus is important in the proper functioning of our brain and nerves.  It fact it is called the “brain element”.  Iron aids in the oxygenation of the body.  Its deficiency is manifested by anemia, docile and sickly condition.  Potassium maintains our heart and muscles healthy and strong.

     As to the vitamin content of garlic, based on 100 grams raw sample, Vitamin B1 (thiamin) and B2 (riboflavin) comprise 0.25 mg and 0.50 mg, respectively. It is Vitamin C that is very rich (15 mg). The Vitamin B family prevents arthritis and rheumatism, enhances sexual vitality, and it is allied to rejuvenation.  Vitamin C on the other hand, prevents scurvy, and aids in the absorption of Iron, thus help in the oxygenation of the body. People who lack vitamin C may experience bleeding gums, slow healing of wounds, frequent colds and infections, and shortness of breath.  

Garlic Smell – a pest repellant
     It is the peculiar smell that makes garlic a natural pesticide. It is one of the insect-repelling plants grown to protect many crops. How is this so?  Here is a tip for gardeners.  Plant some garlic around plots, between rows and among the plants to be protected from insects.  Just the odor of the growing garlic is sufficient to repel destructive insects such as grasshoppers, aphids, mealy bugs, fruit flies and caterpillars, as well as those residing in the soil like crickets and grubs. And if there are thrips and mites around, they are attracted by the garlic that then serves as trap crop, thus saving the other plants like cabbage and beans. The trap crop (infested garlic plant) is then rouged and burned together with the eggs, young and adults of the attacking pests.

     Why don’t you try making your own garlic insecticide?  This is the procedure prescribed by the Rodale Herb Book.

1.      Chop 75 grams garlic cloves and soak in 50 ml vegetable oil for 24 hours.
2.      Mix this in 575 ml water in which 20 grams of powdered soap has been dissolved.
3.      Stir well and strain with old nylon stocking, and store in a glass jar.  Do not use plastic or metal container.
4.      You can dilute this mother mixture one part to 20 parts water, down to 1:100, depending on the level and kind of infestation. 

     Entomologists at the University of California reported that even low concentrations of crude garlic extract could kill at least 5 species of mosquito larvae.  Mosquitoes are vectors of dreaded diseases like malaria, dengue and encephalitis. Further experiments using refined extracts were found to be more effective.  The author has successfully tried the formula against kiti-kiti (mosquito wrigglers) by directly applying the solution in the stagnant water and along canals where the mosquitoes breed.  
  
     Garlic is environment-friendly.  Unlike synthetic ones, like DDT, organic phosphates and hydrocarbons – herbal pesticides are biodegradable and therefore, do not leave toxic residues that destroy the balance of nature and they do not enter into the food chain that may reach our dining table.

     Many people do not like the smell of garlic though. It is really repulsive. The smell of garlic does not go well along fine culture, so some people say. On the other hand, good food does. To avoid the smell, take the garlic oil capsule or gel which is available without prescription.  It is advisable to first consult the doctor since there are people who may be allergic to garlic extract. 

     Garlic is a health food and potent medicine rolled in one. Other than its culinary uses why don’t you try some sautéed garlic in oil or garlic with onion in vinegar?  There goes the saying, “Garlic everyday drives the doctor away.”    

Here are five ways to do it, entomologists (experts on insects) tell us.

1. Plant garlic among your garden plants, say mustard, tomato, pepper, okra, beans, and let it grow with them. Here is a caution though. Don't plant it too close to the crop so as to avoid its allelopathic effect (chemical secretion from its roots to compete with nearby plants).

Garlic serves as natural repellant of insects that would otherwise attack these crops, as well as ornamental plants. You can even harvest the bulbs at the end of the season. By the way, fresh garlic leaves are used in the kitchen like those of its relatives, kutchai (Allium tuberosum) and onion (Allium sepa). Try on fried eggs, batchoy and mami.

2. Hang garlic bulb on trellis and viny crops like patola (Luffa), ampalaya, cucumber, sitao, batao, and the like. Garlic exudes a repelling odor that keeps destructive insects at bay. Now and then crush some cloves in the open to refresh the garlic odor.

3. Make a spray solution direct from its cloves. The simple method is to soak crushed garlic cloves in water for a few minutes, then spray or sprinkle the solution on plants attacked by aphids, mites, caterpillars, and other pests. Adjust strength of solution to the severity of infestation.

Other than its repellant properties, garlic is also anti-bacterial and anti-viral. It could be for this that it was used to ward off the Bubonic Plague carrier - a flea (Xenopsylla cheopis) during the Dark Ages in Europe. It's no wonder people at that time believed in the power of this species of the Lily family in driving away evil spirits.

4. This is another method. Soak approximately 100 grams of chopped garlic cloves in about 50 ml of mineral oil (turpentine or kerosene) or cooking oil for 24 hours. This is then slowly mixed with 500 ml of water in which 20 grams of powdered natural soap (Perla or Ivory) has been dissolved. Soap serves as emulsion to make oil and water miscible. Stir the solution well and strain it with an old shirt or nylon stocking, then store the filtrate in an earthen or glass container and keep it in a cool, dark place.

This serves as mother stock, ready for use, diluting it one part to twenty parts of water, or down to one part per hundred. It is reputed to be an effective insecticide against most common garden pests. It can be sprayed or sprinkled liberally on practically all plants, including ornamentals and orchids.

5. Garlic is planted as "trap crop." In spite of its repellant properties garlic is not pest-free. There are insects that attack it, such as thrips (Thrips tabaci), flea beetle (Epitrix), white flies (Bemesia), and some plant bugs (Hemiptera). Just allow the standing garlic plants to attract these insects, thus saving other crops from being attacked by the same insects. Then rouge the infested garlic plants and burn together with the pest.

Garlic can save us a lot of money, and eliminates the hazard to health and environment caused by chemical insecticides. It is an ancient practice in the Fertile Crescent, Egypt and ancient China, a key to natural and sustainable farming and a balance ecosystem.

Let's revive this simple practice today. ~

Children on a raft among floating garbage

Tom Sawyer and Huckleberry Finn in postmodern times
Dr Abe V Rotor
The twin novels of Mark Twain (Samuel Clemens)  The Adventures of Tom Sawyer and The Adfventures of Huckleberry Finn are envisioned in postmodern version in this photo of children navigating  a waterway of floating gabage on a styropore raft. Far from the Mississippi River scene in early America, these neo-Mark Twain's characters speak of utter neglect of society in preserving our pristine environment, more so, in providing a bright future of our children.

Quo vadis (Where are you going) children?  
They don't hear, they don't understand.
For the essence of adventure is joy,
the danger, the unknown,
curiosity and abandon. ~
