The plant is harvested in the summer and dried for later use[238]. It is taken internally in the treatment of fevers, coughs, asthma, jaundice, impure blood, urinary tract infections, acute appendicitis, biliousness and cancers of the digestive tract[176, 238, 240].

Where can I find this in Bellevue Nebraska? My wife has lung cancer and we would like to try Oldenlandia. We have heard a lot of good things about this product.

I wish Dave luck in finding a supplier. My suggestion is to go to a Chinatown if you have one in a city near you, otherwise contact a Chinese herbalist. Being based in Britain, I have very little knowledge of herbal suppliers in America, but I can tell you of one herbal supplier based in Britain that sends their herbs worldwide. Their name is Incense Magic and their web address is http://www.incensemagic.co.uk/. They supply the herb under its synonym of Hedyotis diffusa.
