Reishi mushroom or "Ling Zhi" mushroom is also known as Ganoderma lucidum. 
It is the King of mushrooms and has been used by herbal practitioners in 
China and Japan for thousands of years. This mushroom is mentioned in the 
first Chinese herbal, dating back to 2800 BC and is classified as a superior 
herb.

It can be taken everyday as an antioxidant to maintain health, increase 
vitality, ease tension, and promote an overall calming effect and sense of 
well-being.

Reishi contains two major groups of organic compounds:

ganodermic acids, classified as triterpenoids. Triterpenes increase oxygen 
consumption, tone the liver, and reduce stress. It is responsible for the 
bitter taste in Ganoderma.
polysaccharides, which are long chains of naturally-occurring sugar 
molecules, which assist in strengthening the natural healing ability and 
health of the body.
DXN adopts a cold treatment which can preserve active elements of Ganoderma. 
The total concentration rate of the cold treatment is 20:1, which is 
superlative to other methods. DXN utilizes cultivation methods based on 
local Malaysian expertise. It has been conferred with GMP certification by 
the Ministry of Health, Malaysia as well as ISO 14001, ISO 9001 and TGA.
