ABSTRACT: Two endemic species of macroalgae in the Nan River, Northern Thailand, Cladophora glomerata Kutzing or "Kai", a branched filamentous alga in the Chlorophyta, and Nostochopsis lobatus Wood em. Geitler or "Lon", a mucilaginous colonial alga in the Cyanophyta, were selected for study as therapeutic agents. The anti-gastric ulcer, anti-inflammatory, analgesic, anti-oxidant, and hypotensive activities suggested their value as therapeutic agents. They may be employed as nutri-pharmaceuticals or food supplements for relieving chronic diseases and disorders including peptic ulcers, dyspepsia, rheumatoid arthritis, hypertension, etc. However, further detailed studies of these pharmacological activities are required to validate their therapeutic potentials.
