Can you take sardinia cambodia if you take high blood pressure medicine?

No. Unless you know what is actually in the pill (and you do not) and the drug has been thoroughly tested for safety and efficacy (which it has not) do not chance it. We do not know what is in these herbal remedies, we do not know what they will do, what they are adulterated with, how much of the unknown stuff or claimed stuff is in there. Don't use them (was i clear?).
