[Function]

Resveratrol is an active component extracted from Huzhang (Polygonum cuspidatum) in China.

It is an antioxidant phenol and a potent vasodilator that inhibits serum triglyceride synthesis, lipid peroxidation, and platelet aggregation.

It is extensively used for treatment of blood vessel disease such as atherosclerosis and hyperlipidemia. In addition, it has anti-virus and anti inflammatory activity, can treat acute microbial infections and viral hepatitis.

Stevia grows best in upland areas in sub-tropical climate. In other places it can be grown as an annual. The plant prefers a lightly textured, well-drained soil to which organic matter has been added. It needs ample water so that the soil is consistently moist, but not wet. In hot, sunny climates it will do best in semi-shade. Propagation is from seed sown in spring, but germination rates can be low-expect half the seeds sown not to germinate. Plant seedlings out once all danger of frost is over. Leaves are best harvested just before flowering. The plants will also grow from cuttings,which are best taken in late winter.The concentration of stevioside in the leaves of Stevia increasing when the plants are grown under long day condition.While, cultivating stevia on a large scale, it can be grown in well-drained red soil and sandy loam soil. The soil should be in the pH range of 6.5-7.5. Saline soils should be avoided to cultivate this plant.

Stevia can be successfully cultivated all around the year all over India expect theareas, which receive snowfall, or temperatures go below 5 degree Celsius in winter.The summer temperatures actually do not affect this plant if the high summer temperatures have already been factored in the cultivation practices.Since seed germination rate is very poor,it is propagated vegetative. Though stem cuttings are used for vegetative tissue culture plants have proven to be the best planting material for Stevia. Tissue culture plants of Stevia are genetically pure, free from pathogens and haveexcellent vigor. The tissue culture plants can be planted throughout the year,expect during peak summer. An ideal planting density is 40,000 plants per acre with spacing of 25×40 cm in a raised bed system. The soil can be enriched with abasal dressing of 25 tons of well rotten farmyard manure/hectare

Soil Type
Stevia requires very good drainage any soil that retain the moisture for very long period of time are unsuitable for Stevia cultivation and should be religiously avoided.Red soil and sandy loam with a 6-7 pH are best for the cultivation of Stevia.

Raised bed preparation
Forming raised beds is the most economical way to grow Stevia. The raised bed should be of 15 cm in height and 60 cm in width. The distance between each plant 23 cm. This would give a plant population of around 40,000 per acre.

Planting Material
There are basically two options for multiplication. The first is the tissue culture and second the stem cutting. Tissue culture is the best option but many farmers are tempted to try the stem cutting method for multiplication. As per practical experience, stem cutting is sometimes more expensive to produce than the tissue culture since the success rate of the stem cuttings establishment is very low, it takes minimum of 25 weeks for the stem cutting to develop in proper feeding roots for transplantation (younger stem cuttings transplants have shown more than 50% mortality in first few weeks of transplants in main field).

Harvesting
Another important aspect of harvesting is the timing of harvest. It should be noted that at no point of time plants should be allowed to flower since after flowering the Stevioside percentage goes down rapidly and leaves are rendered unmarketable. Leaves are harvested by plucking in a small quantity, or the entire plant with the side branches is cut leaving 10 to 15 cm from the base.The first harvesting can be done four to five months after planting. Subsequent harvesting can be done every three months, for five consecutive years. The sweetener in the leaf is maximum till the plant flowers. Just before flowering, the plant should be cut completely leaving 10 cm from the ground. The new flush of leaves will sprout from here. The new plant will be ready for harvest again in three months. The plant yields around 3000 kg of dried leaves from an acre of plantation every year. Harvesting should be done as late as possible, since cool autumn temperatures and shorter days tend to intensify the sweetness of the plants as they evolve into a reproductive state.

Unlocking the sweetness in your harvest
Once all leaves have been harvested it’s required to dry them. This can be
accomplished on a net. The drying process is not one that requires excessive heat;more important is good air circulation. On a moderately warm fall day, stevia crop can be quick dried in the full sun in about 12 hours. (Drying times longer than that will lower the stevioside content of the final product.)
Crushing the dried leaves is the final step in releasing stevia’s sweetening power. The
dried leaves are powdered, sieved and the fine powder is stored in containers. This can be done either by hand or, for greater effect, in a coffee grinder or in a special blender for herbs.

Herbal Health Remedies, Natural Medicine, Natural Treatment for Diseases & its Prevention through the Holistic Medical System — Siddha Medicine. Formulated by Siddhars.

SIDDHA MEDICAL SYSTEM
“Ever since the Human life existed on the Earth, there lived other living beings also, such as plants and creatures side by side. Whenever human body is affected with illness on earth there exists method of curing also against the illness or diseases. The Siddha system is known to be the most Ancient system of Medicine which was devoloped by the Siddhars. The primordial Guru or Agasthiyar is the Father of Siddha Medicine. The Siddhars did various research work on Mother Nature and formulated excellent medicines prepared from plants, animals and minerals. The action and medicinal uses of the plants were realised by them through their emminent Mental and Spiritual power. They formulated the medicines from the herbs thousands and thousands of years ago which are still used in the same way without any expiry in their medicinal value…..!”

Siddha system of medicine is most ancient and spiritually enriched one. Siddha Medicines are formulated and prepared by the Siddhars thousands of years ago after undergoing various research work on flora, fauna and the rich mineral resources of Mother Earth. The medicines are enriched with prayers and power which not only cures the disease but also provides peace to the mind and spirituality to the soul. This divine system of medicine is a treasure of numerous medicines. The medicines which are available today are very few as many of them are still hidden either in the hands of traditional familes or uknown to the present Siddha generation. However, the medicines range from simple preparations like juice of a herb to the higher medicines like parpam and chendooram which can be preserved life-long. The methods of preparation and purification of raw drugs are very important aspect. A siddha physician can be successful only if he understand these techniques. The most interesting fact about Siddha medicines is that all these preparatory methods are explained by the Siddhars in the form of tamil verses or poems. These verses are not very easy to de-code as it needs a good knowledge in ancient Tamil language and also the grace of Siddhars which is very important in order to realise them. This is one of the reasons why Siddha medicines have not been widely established so far. Years passed and this system got confined in the present Tamil Nadu, in hands of small groups of Traditional vaidyars or Practitioners. They treated the Royal kings and even provided kayakarpa treatment. Some traditional practitioners are teaching this science to their children but they have kept it confined within their families only. The secrets of preparing medicines, mode of treatment and the precious books as well as the Siddha literatures have been kept hidden by them. Even today these missing links or hidden secrets are said to be preserved in such families where this traditional system is practiced. They can’t be blamed completely for supressing these secrets. This is because of their fear of disclosing these secrets that may get misused or it may reach in the wrong hands. If the methods of treatment taken into account, then Siddha system holds the 8 unique methods of diagnosis. One among these 8 method is naadi. A Siddha physician keenly observes the naadi before starting any treatment. Hence unlike other system of medicines there does not exist only a symptomatic treatment in Siddha. A strong relationship develops between the patient and physician. The physician not only heals the disease of the patient through medicines but also provides an assurance to his mind and prays for the soul. Hence, “Siddha system” is unique when compared to any other system of medicine as it is both medicinally and spiritually enriched. However, now the merits and the advantages of Siddha medical system is flourishing and awareness of Siddha is progressing world wide.
