[What is Tribulus terrestris?]

Tribulus terrestris is a vine that has been used as a general tonic (energy) and herbal treatment for impotence, but is found primarily in dietary supplements marketed for increasing testosterone levels in bodybuilders and power athletes. The idea behind tribulus is that it may increase testosterone levels indirectly by raising blood levels of another hormone, luteinizing hormone.

[Function]

1) Enhance men’s sexual ability.

2) Relieving muscle spasm and cramps;
3) Anti-myocardial ischemia and cerebral ischemia;
4) Relieving stress , regulating blood fat, and reducing cholesterol;
5) Promoting sex gland hormones;
6) Anti-aging and anti cancer;
7) Diuretic, anti-calculus of the urethra, reducing the risk of urinary stone disease and disorder;
8) Promoting muscle growth efficiently, helping the body to be strong and letting muscle to play potential role.

In this video Ryan from RAW Forest Foods shows you how to traditionally prepare Goji. This traditional preparation use used for endocrine repair/regrowth, specifically for decalcifying the Pineal gland. Extended information on this can be found at our blog (https://goo.gl/udxBX).
