Present day Ayurveda is a big scam. The real Ayurveda which was superior than allopathy was destroyed during the Buddhism era unleashed by Samrata Ashoka. Because as per the principles of Buddhism at that time suffering would give you moksha and suffering due to sickness etc. was a redemption of your past karma. In fact ayurveda had surgery procedure and was very advanced. Unfortunately all the artifacts and documents were destroyed. In most countries Ayurveda(internal medicine) is banned, since they found mercury, lead and other heavy metal. So Ayurveda per se may be ok but the mass manufacturing introduces too many toxicity to be considered safe.
