Abstract: The present invention relates to a method for the treatment and/or prevention of disorders with elevated PGE2 and/or LTB4 levels, comprising administering to a mammal an effective amount of pterostilbene component (PS component), a pharmaceutically acceptable salt of PS component or a precursor of PS component, wherein the PS component has the formula in which R1, R2 and R3 are independently selected from hydrogen, C1-50 hydrocarbyl, C1-50 substituted hydrocarbyl, C1-50 heterohydrocarbyl, C1-50 substituted heterohydrocarbyl; and wherein at least one of R1 and R2 is not hydrogen

Abstract: The present invention is concerned with the treatment or prevention of cancer, H. pylori infections, chronic inflammatory conditions, cardiovascular diseases or cerebral vascular diseases in a mammal, comprising the administration of the mammal of an effective amount of a composition containing a matrine component and dictamnine. Another aspect of the invention relates to a composition comprising at least 15 &mgr;mole of a matrine component and at least 0.15 &mgr;mole of dictamnine.

Abstract: The present invention is concerned with a process for the manufacture of a herbal composition, said process comprising: a. subjecting a matrine containing plant material, in the absence of a plant material derived from the species Dictamnus, to an extraction with an aqueous solvent, optionally followed by a concentration step, to produce a herbal extract I; b. subjecting a plant material derived from the species Dictamnus, to an extraction with an aqueous solvent, optionally followed by a concentration step, to produce a herbal extract II; c. mixing the herbal extracts I and II; d. provided the resulting mixture contains a significant amount of water, drying the mixture to a water content of less than 6 wt. %. The herbal composition according to the present invention may advantageously be used in a method of treating or preventing cancer, H. pylori infections, chronic inflammatory conditions, cardiovascular diseases or cerebral vascular diseases in mammals.
