W. Goto et al., SUPPRESSION OF HEPATITIS-B VIRUS SURFACE-ANTIGEN SECRETION BY TRADITIONAL PLANT MEDICINES, PTR. Phytotherapy research, 10(6), 1996, pp. 504-507
Forty-three extracts of herbal medicines were tested for suppressing t
he secretion of hepatitis B virus (HBV) surface antigen (HBsAg) in vit
ro, Fourteen extracts were found to have appreciable effects in the ex
perimental system using the PLC/PRF/5 cell line, Of them, the extracts
of Rheum palmatum (rhizome), Poligonum cuspidatum (root), Panax japon
icum (root) and Terminalia arjuna (bark) strongly suppressed the secre
tion of HBsAg, The active constituents of these extracts absorbed thro
ugh the gastrointestinal tract of guinea-pigs suppressed the secretion
of HBsAg in the PLC/PRF/5 cell culture.
