About Rosemary extract

Rosmarinus officinalis, commonly known as rosemary, is a woody, perennial herb with fragrant, evergreen, needle-like leaves and white, pink, purple, or blue flowers, native to the Mediterranean region,which active ingredients including Ursolic Acid, Rosmarinic Acid, Carnosic Acid


Rosmarinic acid

Rosmarinic acid is considered to be a natural, efficient and stable (high temperature durable), security, non-toxic andside-effects, water-soluble antioxidants and a green food additive. 

The medical research indicates that, it can eliminate the free radicals that over-produced by the body and annihilate the singlet oxygen to protect the structure of the cell membrane,which can slow down the aging process.

In addition, it can stimulate and accelerate the metabolism of the fat by anti-oxidant activity. Not only can it lower the blood pressure, but it can also promote the lipid compounds to emit from the manure so as to lose weight
