I am considering to take a mood enhancer that contains mainly st johns wort and siberian ginseng, will it interact with twynsta?

DISCUSS WITH DOCTOR: You really need to discuss this with your doctor. Whenever taking over the counter meds they may intereact with your prescribed meds and even though they are over the counter and called "herbal" there could be a real problem. St John's Wort effects serotonin and also the Ginseng has some blood thinning effects.

Mood & BP issues: St John;s Wort is ancient in use for stress and has been a trigger of mania and/or psychosis. Siberian ginseng is used for stress, it is not what is usually called a ginseng. It is has other uses including lowering blood pressure. Twynstra is used to lower blood pressure so the combination could cause problems. Using these in combination needs to be carefully monitored by your physician.
