In many countries, TM/CAM medication therapies are commonly used in combination with conventional medicine, generally with satisfactory results. However, it is important to be aware of the possibility of interactions that may result from the concurrent use of several TM/CAM medication therapies and/or conventional drugs. The combination of several TM/CAM medication therapies and/or the concurrent use of conventional drugs may magnify or oppose the effect of the treatments (24). Consumers need to be informed about any potential interactions involved in their therapy and they also need to understand the importance of informing health care providers and TM/CAM providers about any parallel use of therapies and/or medicines. Because of the limited knowledge about interactions between conventional medicines and herbal medicines, this is an area that needs further study and it is important that professionals as well as consumers pay careful attention to this area and report any suspected interactions.
