You have to be careful with herbs because they can literally act like a "drug" and have interaction with any meds you're already on. Please try to read what you can about any herb you consider taking and ask your pharmacist if there are any interactions you need to look out for or worry about. I hope you have luck with whatever you decide, I suffer from migraines and understand wanting them to stop.
Eastern medicine does not recognize Western medicine and vice versa. Most of our physicians are really not formally trained about herbs. Besides the pharmaceutical companies that sponser most education conferences cannot make any money on an herb. Also that being said many herbs have no standards to be held to. Now playing devils advocate how many drugs- FDA approved pharmaceuticals have hurt people and been pulled off the market or had a black box warning placed on them. Back to your question Yes, I always go plant / herb first. I also have studied plants and herbs for many years. I also make sure that what goes in my body is quality and my physicians are aware.
