Manufacturers do this to inform current owners and prospective buyers of the potential risks of using car seats and booster seats that may be missing important parts, labels or instructions and/or may have an unknown history, which could lead to less than optimal safe performance when needed.
Since 1955 a a refined extract of the chaga fungus has been manufactured and sold in Russia, Eastern Europe, and Japan for the treatment of stomach and intestinal diseases. There is now scientific research to support the claims of the folk medicinal uses.
In 1999, while we were buying Chanterelle mushrooms for a larger mushroom company out of Richmond, B.C. I heard of Chaga from a Russian biology exchange student in the Queen Charlotte Islands, (located off the north coast of British Columbia, Canada). I'd been a professional mushroom harvester and field buying agent of wild gourmet mushrooms since 1997. After finding a very rare fungus there, that he named Ling Zhi (a medicinal mushroom most favored in China & Japan), he told me a very interesting story about another potent medicinal mushroom-Chaga.
