A vast majority of the world's population uses complementary and alternative medications as aides or alternatives to modern medicines. The medications can have strong effects in your body. They can also interact with other medications. The synergistic action of the alternative and allopathic medications may decrease your blood pressure drastically. So, consult your alternative medicine doctor regarding the effects and drug interactions of your complementary and alternative medications. Likewise, inform your allopathic doctor about any Ayurvedic/homeopathic medications or supplements that you are taking or interested in taking.
