An experimental study of the anti-HSV-II action of 500 herbal drugs

Experimental assessments were made on the anti-HSV-II action of 500 herbs by determinations of the virus inhibition logarithm (VIL). 13 highly effective herbs (VIL greater than or equal to 4.00) were screened cut, providing a rational basis for clinical therapy. Among these effective herbs, 10 were aqueous extracts of Artemisia anomala, Centella asiatica, Epimedium Sagittatum, Hibiscus mutabilis, Hosta plantaginea, Hypericum japonicum, Inula japonica, Mosla punctata, Rhododendron simsii, and Rhus chinenses, while 3 were alcohol extracts of Epimedium Sagittatum, Hypericum japonicum, and Mosla punctata.
