  • Patent number: 6432455
    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.
