Osthole - also spelled osthol - is a kind of coumarins. Osthole is found in cnidium monnieri and several other plants. Osthol could increase androgen, gonadotropin and nitric oxide synthase (NOS) activity. Osthole is a libido stimulator.Researchers investigate the cavernosal relaxant effect of osthole, has been long used in China as a herbal medicine to improve male sexual dysfunction. The data suggested that osthole posseses a relaxant effect on rabbit corpus cavernosal tissues which is attributable to the release of NO from sinusoidal endothelium and to the potentiation of the cGMP and/or cAMP signal mediating relaxation of cavernosal smooth muscle by inhibiting phosphodiesterase".

Osthole benefit for fatty liver

Osthole improves fat milk-induced fatty liver in rats: modulation of hepatic PPAR-alpha/gamma-mediated lipogenic gene expression.

Planta Med. 2007 July. Department of Pharmacology, Medical School of Soochow University, Suzhou, PR China.

The objectives of this study were to determine the therapeutic effect of osthole, an active constituent isolated from Cnidium monnieri (L.) Cusson (Apiaceae), in hyperlipidemic fatty liver rats and investigate the possible mechanism of the osthole treatment. Osthole exerts therapeutic effects on fat milk-induced fatty liver in rats, by regulating mRNA expression of the target genes of CYP7A, DGAT, L-FABP and FATP4 via increasing the PPARalpha/gamma mRNA expression.

Osthole research liver cancer

Chemical aspects of coumarin compounds for the prevention of hepatocellular carcinomas.

Curr Med Chem Anti-Canc Agents. 2005 Jan;5(1):47-51.

The normalization of plasma alanine aminotransferase (ALT) has been proved to be a strategy for preventing the development of hepatocellular carcinoma (HCC) in hepatitis C virus (HCV)-infection. Glycyrrhizin, a plant medicine, normalizes plasma ALT and prevents HCC. However, glycyrrhizin is administered intravenously and thereby chemical which is effective on oral administration is required. Coumarin compounds are active components of herbs used for the treatment of various diseases. The ability of coumarin compounds to lower plasma ALT were examined using mice concanavalin A-induced hepatitis and mice anti-Fas antibody-induced hepatitis.We conclude that osthole will become a leading chemical for synthesizing a compound which prevents liver cancer on oral administration.

Osthole mental effects

Osthole improves aspects of spatial performance in ovariectomized rats.

Am J Chin Med. 2004;32(1):11-20.

The present study was designed to investigate the ameliorating effects of Cnidiuim monnieri L. Cusson (CM) and osthole, a constituent of cnidium, on the spatial performance deficit in scopolamine (SCOP)-treated or ovariectomized rats. Osthole improved the performance deficit in ovariectomized rats. The action mechanism of the effects of osthole on performance deficits was related to the estrogen-like properties and activating the central cholinergic neuronal system.

Osthole relaxes trachea

The relaxant action of osthole isolated from Angelica pubescens in guinea-pig trachea.

Naunyn Schmiedebergs Arch Pharmacol. 1994 Feb;349(2):202-8.

The effect of osthole, isolated from Angelica pubescens, on the contraction of guinea-pig trachea was studied. Osthole, theophylline and higher concentrations of nifedipine suppressed the contraction response curves of tracheal smooth muscle caused by carbachol, prostaglandin F2 alpha (PGF2 alpha), U46619 (thromboxane A2 analogue) and leukotriene C4 (LTC4) in a concentration-dependent manner. It is concluded that osthole exerts a non-specific relaxant effect on the trachealis by inhibiting the cAMP and cGMP phosphodiesterases.

Plants that contain osthole

A number of herbs contain osthole, including cnidium and angelica pubescens root.
