Folk use of fuzi

I was talking to a guy who used 15g of fuzi to treat his 86 year old grandmother when she had a stroke. He said that after the treatment she didn't have any signs of hemiplegia.

He also did channel massage for her.

Two years later she died from heart failure and other complications at the age of 88. He said he gave her up to 30g of fuzi at that time, but didn't dare give her any more.

He is a fan of Li Ke (李可), makes his own medicinal wine for personal consumption, and has had no formal medical training.
