Abstract: The invention is directed to chemical processes of preparing fractions form North American ginseng (Panax quinquefolium) and pharmaceutical compositions containing these fractions. The products of the present invention may be used to stimulate the production of cytokines and/or antibodies, or as therapeutics targeted at conditions characterized by low immunity, such as the common cold, influenza, chronic fatigue syndrome, AIDS and cancer.

Abstract: A preparation derived from shark cartilage for the treatment of diseases related to excessive PHF or Excessive intracellular calcium.

Abstract: Hypericin has been shown to specifically inhibited T-type calcium channel activity. Hypericum extract containing hypericin also inhibited T-type calcium channel activity. Moreover, other chemicals in Hypericum extract showed a synergistic effect to hypericin. In view of this, hypericin or hypericin-containing Hypericum extract can be used as T-channel blockers. Hypericum extract, extract of other species of the Hypericum genus, extract of other plants containing hypericin, hypericin, hypericin derivatives, hypericin analogs, such as pseudohypericin, and other hypericum extract constituents can be used as therapeutics targeted at T-type calcium channels for treatment of diseases associated with T-channel abnormality. Methods for administering hypericin and hypericum extract are disclosed.
