It must be kept in mind that herbs are powerful, and in some instances there may be a drug and herb interaction which can cause unwanted side effects. For this reason it is necessary to keep your health practitioner and pharmacist informed of any supplements or other medication that you may be taking.
Below, we have compiled a very small list of herbs and drugs that may interact, but visitors must please note that it is not an exhaustive list, and that they at all times, when taking medication and supplements, in whatever type or form, must discuss it with your health practitioner should they have any side effect.
We have information on individual herbs that you can access by clicking here, and if you wish to look at our product list, please click here.
