Barlowe's Herbal Elixirs proudly offers a very hard-to-find 10:1 Cynomorium Songaricum Extract (Herba Cynomorii). In Traditional Chinese Medicine (TCM), Cynomorium is used primarily to treat a deficiency of Kidney Yang energy. It is also said to be beneficial for the joints - especially the knees. One reknowned herbalist produced a famous remedy made with Cynomorium (Hidden Tiger Pills) which was utilized for weakness of the legs and knees. The name was based on a tiger in the crouched position, since remaining in a crouched position requires substantial strength in the tendons, ligaments, and muscles of the legs. Cynomorium is considered to be a superb tonic for building primal yang essence in both men and women and it is also considered to be a longevity herb. The Cynomorium Certificate of Analysis (COA) of this particular batch is shown above. ***These vegetable-derived capsules (Vegan, Kosher and Halal certified) are filled on slow speed equipment and only pure, unadulterated herbal extract is contained in the capsules. There are no magnesium stearates, fillers, gelatin, silicates, gluten, corn, wheat, rice, yeast, starch, titanium dioxide, artificial colors, artificial flavors or preservatives. Capsules produced with high speed equipment in herbal and dietary supplement "factories" generally contain several other ingredients, including powdered lubricants called STEARATES (which can greatly diminish an herb or supplement's absorption into the body). Check their labels! Barlowe also still bottles his products in glass as he believes chemical vapors can vent from plastic containers and contaminate the contents and that glass is better for the environment.
