Wheatgrass is astringent and bitter, so it increases Vata but balances Pitta and Kapha. I recommend wheatgrass as a component of cancer treatment and prevention. I also recommend wheatgrass to Pitta and Kapha types: those who have history of inflammatory issues (e.g. hypertension, ulcers, any "-itis") or growths (e.g. blocked arteries, cysts, stones).
