Hi,
The most important reasons for me to say about this product are;
1. it is the only Chinese Yunzhi product the USP (United States Pharmacopeia) verified its ingredient and produced in the way like the western drug manufacturers in Hong Kong (not mainland China).
2. Yunzhi is known for a long time as a immumostimulant;to help the body immune system.
3. the related research and production guidelines were performed by the pharmacy department of the Chinese University of Hong Kong.
4. but please remember this is a COMPLIMENTARY ADJUNCT SUPPLEMENT and not an ALTERNATIVE medicine to replace chemotherapy.
for more info. go to http://www.oncozac.com ; the ino. are in English.
I personally do not have any financial involvement in the company;it is the USP approval of the ingredient that caught my eye on this product.
God bless.
