Does Wheat Grass Eliminate DHT?

I’ve heard that drinking wheatgrass juice eliminates DHT completely from the system. Is this true?

It appears to be recommended as an alternative or a dietary supplement for individuals with prostate problems. Like all herbal remedies, there is more folk lore than facts backing up such claims. I would presume that claims for blocking DHT would deal with prostate problems and hair loss, just like proven approaches with the drug finasteride.
