I whole heartedly agree with you there Wendy. Make sure you have a reputable practitioner. There are many ”snake oil salesmen” out there, who will swear their ”product” works the best, When in all actuality it might kill you. Use common sense, study, learn, and above all, don’t believe everything you read, or hear.
For the most part, common, easy to get Herbs are safe, with few side effects. However… there are some that will cause interactions with common drugs, even over the counter ones, and then you have some that can be deadly in their own right. Nightshade, and oleander just to name two of them. ( Oleander is being looked into right now for possibilities with cancer treatments )
Think, learn, and be informed, and check backgrounds for anyone you choose to treat yourself, or your family.

Yes Wendy I absolutely agree. Each person reacts differently to meds it doesn’t mater if they are natural or not. I can eat fennel with out a problem, but I can NOT take fennel tea for tummy upsets. I get a skin reaction to it, even the smell can set me off. Hubby can’t take chamomile! Many herbs have been a wonderful blessing to us, but it takes a lot of research to learn what is best of each problem for each person as our bodies react differently.
