I think you have the wrong view on herbs. Herbs are generally not cures. Their simply plants that people have found to have an healing effect on the body. Once the body is healed it can cure itself.
True some herbs are too powerful to be used long term thats why you have to know which ones to take.
Theirs a ton of misinformation on herbs so thats why i recomend finding someone who trained and can help you.
Adaptogen herbs are a class of herbs that are considered to be very beneficial and safe to use long term.
Electro devices like the Pulser and Rife are great. But i wont look pass herbs. You just have to learn which ones you need.
There has been a lot of long term use of herbs it dates back 5,000. Remember herbs are simply foods that heal. Some better then others.
