The majority of gardeners on GoY are in the UK, most of the rest are in the USA or Australia/New Zealand... there is no way we can answer your question. Which, I might add, has been asked several times before!

There are seed retailers who sell the seeds for this and other medicinal plants for the practice of Ayruveda. There are also some shall I say- businesses - which deal in the phytochemical extracts of this and other plants for use in this and other forms of alternative medicine. You should have no trouble finding those located in India on your search engine ... Now Get To Work finding them.... As moon grow has said this is a Gardeners web site...not an agency for procurement. For GOY...this plant which grows in that part of the world is commonly known as the Globe Thistle plant. With the growing popularity of the practice of Alternative Medicine around the world, it is probably being picked clean from the areas where it grows and is becoming very hard to get and costly to be gotten...especially since this plant is thought of to have the properties of an aphrodisiac:) For MG, As you have intimated, this is a world wide web site, so I would not slam the lid down completely on what it's members know. As for me, I am constantly amazed at what GOY members know each time I visit this site.

Your best bet is to look for it on Google. There are many more sites on Ayurveda in India than here where we know little about sources of plants.Good luck with making your medicine!
