In general, it is okay to take several formulas concurrently provided they do not contain overlapping ingredients or functions. Check the primary ingredients for each formula to be sure you're not getting too much of one particular herb. If there are overlapping ingredients, you may lower your dosage appropriately.Similarly, try not to take full strength dosages of formulas which serve the same function (e.g. pain, laxative, etc.). Even though the ingredients may not be the same, they could have similar effects on your body - so it's best not to overdo it.As with any herb or remedy, it's always a good idea to listen to what your body is telling you. If taking more than one herbal formula concurrently is causing discomfort, you should reduce the dosage and/or discontinue use.For individualized instruction on taking multiple herbal formulas, we recommend you see your physician or trained herbalist.
