ABSTRACT

Phytogenic agents have traditionally been used by herbalists and indigenous healers for the prevention and treatment of

peptic ulcer

. Botanical compounds with antiulcer activity include

flavonoids

(i.e., quercetin, naringin, silymarin, anthocyanosides, sophoradin derivatives), saponins (i.e., from

Panax japonicus

and

Kochia scoparia

),

tannins

(i.e., from

Linderae umbellatae

), and

gums

and mucilages (i.e., gum guar and myrrh). Among herbal drugs,

licorice

,

aloe

gel

, and

capsicum

(chili) have been used extensively and their clinical efficacy documented. Also, ethnomedical systems employ several plant extracts for the treatment of peptic ulcer. Despite progress in conventional chemistry and pharmacology in producing effective drugs, the plant kingdom might provide a useful source of new antiulcer compounds for development as pharmaceutical entities or, alternatively, as simple dietary adjuncts to existing therapies (Borrelli and Izzo, 2000).
