Asian Ginseng
Imatinib
A case report suggested that Panax ginseng may inhibit the metabolism of imatinib, potentially increasing the toxicity of the drug. People taking imatinib should therefore not take Panax ginseng.

Asian Ginseng
Ticlopidine
Ginseng (Panax ginseng) was associated with a decrease in warfarin activity in a case study. This report suggests that ginseng may affect parameters of bleeding. Therefore, people taking ticlopidine should consult with a physician knowledgeable about botanical medicines before taking Asian ginseng or eleuthero/Siberian ginseng (Eleutherococcus senticosus).

Asian Ginseng
Warfarin
Asian ginseng was associated with a decrease in warfarin activity in a case report. However, in a clinical trial, no interaction was seen between Asian ginseng and warfarin. An animal study also found no significant interaction between warfarin and pure ginseng extract. Nevertheless, persons taking warfarin should consult with a physician knowledgeable about botanical medicines if they are considering taking Asian ginseng or eleuthero/Siberian ginseng (Eleutherococcus senticosus). A 1999 animal study did not reveal any significant interaction between warfarin and pure ginseng extract.

Chlorphen-Pyrilamine-PE Tannts
Laboratory studies have shown that compounds found in Panax ginseng enhance the ability of phenylephrine to constrict blood vessels. Controlled studies are necessary to determine whether taking Panax ginseng at the same time as phenylephrine will enhance the beneficial effects of the drug.

Influenza Virus Vaccine
In a randomized, double-blind study, 227 people received influenza vaccine plus 100 mg of standardized extract of Asian ginseng (Panax ginseng) or placebo two times per day for four weeks before and eight weeks after influenza vaccination. Compared with placebo, Asian ginseng extract was reported to prevent colds and flu, improve immune cell activity, and increase antibody levels after vaccination.

Lamivudine
Test tube studies show that the herbal combination sho-saiko-to enhances the antiviral activity of lamivudine. Sho-saiko-to contains extracts of seven herbs, including Bupleuri radix, Pinelliae tuber, Scutellariae radix, Zizyphi fructus, ginseng (Ginseng radix),licorice (Glycyrrhizae radix), and ginger (Zingibers rhizoma). Controlled studies are needed to determine whether taking sho-saiko-to might enhance the beneficial effects of lamivudine.
