Several medical doctors I know (including surgeons) recommend Ayurvedic treatments on occasions and I've found them to generally work well (though they generally are skeptical of homeopathy).
Do you have reason to believe that herbal remedies don't work?
Remedies that have been subjected to scientific experimentation to determine if they are effective are by definition "evidence-based", or "modern" medicine. Any medicine that is not evidence-based should be treated with suspicion and skepticism, and frankly should not be called medicine at all in my opinion.
