Can you take st wart and ginkgo together?

St John's Wort and Ginkgo Biloba may interact with each other and cause bleeding risk to be increase

Both Ginkgo Biloba and St John's Wort have interactions with several medications (St Johns wort interacts with more than 800 medications) so you really need to find out what other products your father is taking before even considering offering these substances

If you would like you can send me a private list of all known substances so that I may assess them for any issues or concerns in combination
