Today I noticed the following comment on my entry about Tribulus terrestris:
Respected Sir,
Please include the information about chemical composition or tribulus
as well as biochemically changes during growth and development in
tribulus terrestris. If you have the same literature please send me as soon
as possible.
Thanking you
Yours sincerely

A quick check of my referrer log shows me "tribulus terrestris" has been the top or second highest search term for my site in the last two months respectively.
Tribulus terrestris is a common weed that almost all of us in the states are familiar with. Also known as goathead or puncture vine, Tribulus is seeing a widespread adoption rate in some questionable (IMHO) products as a natural testosterone booster. (Ahem)
I like goathead more for it's use in arteriosclerosis. I picture the little caltrops rifling through the blood vessels, scraping the plaque off the walls. I've used it for a few years now and haven't really noticed a boost in my... er, manhood. Not that I need it mind you. My libido is just fine, thank you very much.
While I can't help much with the full-spectrum analysis of the phytochemical constituents that Jitendra is looking for, I can give some insight into the best time to collect the seeds. You want the seeds to be well-formed, but not hardened. Ripe caltrops are nearly indestructible, even to the stoutest of coffee grinders. I pick them when the spines offer some resistance, but won't prick my finger. It's an art, but simple enough to figure out when you've waited too long.
Good luck in your searching. But if you're looking for a testosterone boost, I wouldn't get my hopes (or anything else) up too high.
