Generally speaking, herbal remedies are safe, but some have side effects depending on the following:
Quality control: where they’re grown, manufactured, and distributed
Efficacy of self-prescribed herbs vs. a licensed practitioner
Drug-herb interactions
In reference to drug-herb interactions, consult your doctor if you’re currently:
Taking blood pressure medication such as blood thinners or aspirin
About to have a surgical procedure to avoid bleeding complications
Pregnant or breastfeeding
There are a lot of beneficial Chinese herbal formulas that you can safely take while you’re on prescribed medications. Many Chinese herbal formulas are food-grade quality herbs that may be taken to prevent miscarriages, and to support pregnancy and postpartum recovery.
