Seabuckthorn contains oleanolic acid that help improve blood circulation and tone the body. Ursolic acid has a beneficial effect on the functioning of the adrenal gland hormones. It also has a very powerful effect in healing wounds, ulcers and in liquidating erosions. The mechanism of hepatoprotection by these two compounds help the inhibition of toxicant activation and the enhancement of the body defense systems. Oleanolic acid and ursolic acid have also been long-recognized to have anti-inflammatory and anti-hyperlipidemic properties. Recently, both compounds have been noted for their antitumor-promotion effects, which are stimulating additional research in this field.
