  • Patent number: 6262019
    Abstract: Glutathione (GSH) is a tripeptide of extreme importance as a catalyst, reductan, and reactant. It can be depleted intracellulary either by forming a direct complex with an electrophilic agent (accomplished investigationally by agents such as bromobenzene or diethyl maleate), by way of inhibition of synthesis, or by subjecting cells to oxidant stress. Most cells, except for epithelia cells, do not have a direct transport capacity for intact GSH. Non-epithelial cells must either transport precursor substrates for GSH synthesis or salvage amino acids from circulating GSH for reuse in intracellular resynthesis. Dietary cysteine is a rate limiting substrate for the synthesis of glutathione and also inhibits GSH efflux. Although GSH is synthesized from precursors in virtually all cells, the liver is the main source of plasma GSH. Protection and support of liver function is paramount to elevating GSH levels.

  • Patent number: 6180106
    Abstract: The composition disclosed is a unique formulation of Traditional Chinese Medicine (TCM) extracts created to reduce the debilitating symptoms of allergies. It combines a number of organically grown, but, non-organically extracted, standardized formulations of natural ingredients which have been used singly for hundreds of years for symptomatic relief of allergies. These include Ginseng and Gan Cao, which provide a natural anti-inflammatory effect; Bai Gao, which prevent the smooth muscle spasms associated with allergic reactions; Suan Zao ren, which provides an antihistamine effect without the usual sedative effect; and Wu Mai, which reduces the local swelling associated with allergies. Combined, it was unexpectedly found that these ingredients provide a natural, non-drying, non-sedating alternative to antihistamines, without inhibiting the natural healing mechanisms.
