Ayurveda is the most ancient science of healing in a natural way which originated about 5000 years ago. It is the part of veda which means knowledge. So ayurveda means knowledge of life (ayu). Still today, ayurveda is the main medicinal system in India, China and some other Asian countries which has a tradition on this subject. Research is still going on various plants. Special attraction was given from the ancient time on Tulshi which alone can heal almost 500 diseases spread over many species. The most famous are Black (shyam) Tulshi, Sursa (swet) Tulshi, Ram Tulshi, Bon Tulshi & Nimbu Tulshi , mixture of these five Tulshi can create a magic which effectively can cure 200 diseases. So many companies have products depending on these five tulshi in Indian markets. The best one, to my view is that of IMC which is WHO GMP & HACCP certified. No other products of any company has these two certificates simultaneously. I have been using this for last year and successfully treated 40 diseases completely. It is available in particular shop of this company in various cities of India.
