Barlowe's Herbal Elixirs now offers a high potency 10:1 Bombyx Mori (Bombyx Batryticatus) Extract. The Bombyx Mori Certificate of Analysis (COA) of this particular batch is shown above. Bombyx Mori (Jiang Can) has been utilized in Asia for hundreds of years as a tonic herb. It is a rare, much sought after silkworm extract used to energize the body. Full of nutrients, vital minerals and Amino Acids, it also acts as a vasodilator - increasing blood flow. ***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.
