Ayurvedic Practitioner Dr Valerian Mendonca: Papaya Leaves for Chikungunya

2016/01/img_1959.png

“…Herbal medicine in India has been saving lives for thousands of years. Ayurveda is probably as old as the Indus Valley Civilization dating back to 3000 BC. All four Vedas especially the Rig Veda carry references to diseases and their cures through herbs and roots.

The ancient art of Ayurveda was systematically killed by the colonialists when they took over the country. It was suppressed by the British. The East India Company banned and shut down all Ayurvedic colleges in 1833. When Ayurveda re-emerged for almost 100 years, herbal remedies were dismissed as “the poor man’s medicine” practiced in rural areas where western medicine was too expensive or not available. The irony was the country folk were healthier than the urban class.

The Portuguese in Goa actually did shut down Ayurvedic practitioners. The Vaidyas of Hindu Pharmacy were the only Ayurvedic dispensers allowed to practice after one of them saved the life of a Viceroy’s wife.

Only now more and more patients are realising that allopathy or Western Medicine is not just expensive, but has hidden side effects that cause more problems than the original ailment itself.

When the Chikungunya outbreak happened a couple of years ago, The Times of India Mumbai edition carried an article on the effectiveness of the papaya leaf juice cure to completely eliminate the crippling joint pains that kicked in after the fever ended. My brother read the article and was so desperate to try anything to get back to his active life that he experimented with the papaya cure. It worked the same day. He had another two tablespoons the next day and was 100 percent fit.”

Papaya Leaf as Natural Pesticide in Jamaica

https://m.flickr.com/photos/smallerworldtours/5405407234/

The Island of Jamaica has an abundance of wild and farmed papaya trees with leaves that can provide not only a healing tea but also a very powerful and natural insecticide to prevent the spread of mosquitos that propagate dengue fever, chikungunya virus and malaria. The research below, specific to Jamaica, was done in 2011 at Yerba Buena Farms.

Papaya
This is another plant that grows quickly and easily. Because it is farmed commercially, it is very common. Jamaican cultural uses of the plant do not include using it as a pesticide. We will experiment with using the stain from the tree and the green fruit and the essential oil from the leaves.

• Papaya
Plant parts with insect controlling properties: leaves, seed, unripe fruit flower.
Target pests: thrips and fruit fly, mosaic virus and powdery mildew.
Preparation: 1 kg of finely shredded leaves, placed in 1 litre of water and squeezed through a cloth. Take 1 litre of soap solution, dilute it in 10-15 ml water.

Ayurvedic medicine recommends papaya leaf for Chikungunya virus

According to the CDC, The most common presenting features of Chikungunya are:
• Fever (92%) usually associated with • Arthralgia (87%),
• Backache (67%) and
• Headache (62%).
One of the clinical measures to determine Chikungunya virus is a low white cell count (leukopenia). (leukocyte count below 5000 cells/cu mm)

Papaya leaf tea has shown effect to raise white blood cell count when tested on Dengue Fever:

“…administration of papaya leaf juice was beneficial in dengue patients in elevating the total white cell counts and platelet counts.”

When the Chikungunya virus erupted in India, the times reported the use of papaya leaf as relief. See this Dr’s article:

Papaya Leaf Relief for Chikungunya Virus

Chikungunya virus infection can cause a debilitating illness, most often characterized by fever, headache, fatigue, nausea, vomiting, muscle pain, rash, and joint pain. The term ‘chikungunya’ means ‘that which bends up’ in the Kimakonde language of Mozambique.

Acute chikungunya fever typically lasts a few days to a few weeks, but as with dengue, West Nile fever and other arboviral fevers, some patients have prolonged fatigue lasting several weeks. Additionally, some patients have reported incapacitating joint pain, or arthritis which may last for weeks or months. The prolonged joint pain associated with chikungunya virus is not typical of dengue. No hemorrhagic cases related to chikungunya virus infection have been conclusively documented in the scientific literature. Co-circulation of dengue fever in many areas may mean that chikungunya fever cases are sometimes clinically misdiagnosed as dengue infections, therefore the incidence of chikungunya fever could be much higher than what has been previously reported. -CDC

Studies show that relief from the virus can come by drinking papaya leaf juice or papaya leaf tea as it raises back white blood cell count. See the related below:

Relief from the virus can also come by getting rid of the Mosquitos who carry it. The study below from Bharathiar University India is to test papaya leaf effect as an insecticide on the the Aedes aegypti mosquito which transmits the Chikungunya virus.

ABSTRACT The present study was carried out to establish the properties of Carica papaya leaf extract and bacterial insecticide, spinosad on larvicidal and pupicidal activity against the chikungunya vector, Aedes aegypti. The medicinal plants were collected from the area around Bharathiar University, Coimbatore, India. C. papaya leaf was washed with tap water and shade-dried at room temperature. An electrical blender powdered the dried plant materials (leaves). The powder (500 g) of the leaf was extracted with 1.5 l of organic solvents of methanol for 8 h using a Soxhlet apparatus and then filtered. The crude leaf extracts were evaporated to dryness in a rotary vacuum evaporator. The plant extract showed larvicidal and pupicidal effects after 24 h of exposure; however, the highest larval and pupal mortality was found in the leaf extract of methanol C. papaya against the first- to fourth-instar larvae and pupae of values LC(50) = I instar was 51.76 ppm, II instar was 61.87 ppm, III instar was 74.07 ppm, and IV instar was 82.18 ppm, and pupae was 440.65 ppm, respectively, and bacterial insecticide, spinosad against the first to fourth instar larvae and pupae of values LC(50) = I instar was 51.76 ppm, II instar was 61.87 ppm, III instar was 74.07 ppm, and IV instar was 82.18 ppm, and pupae was 93.44 ppm, respectively. Moreover, combined treatment of values of LC(50) = I instar was 55.77 ppm, II instar was 65.77 ppm, III instar was 76.36 ppm, and IV instar was 92.78 ppm, and pupae was 107.62 ppm, respectively. No mortality was observed in the control. The results that the leaves extract of C. papaya and bacterial insecticide, Spinosad is promising as good larvicidal and pupicidal properties of against chikungunya vector, A. aegypti. This is an ideal eco-friendly approach for the control of chikungunya vector, A. aegypti as target species of vector control programs.
