money concentric peoples are always keen in emerging fields so Ayurveda is now good medium to earn money. most people believes that Ayurveda medicine has no side or bad effects. its true not in all manner.
Ayurveda is an science. every science follows the rules. each & every action has equal and opposite reaction. so Ayurveda also follows the same rule. every Ayurvedic medicine has its own properties, indications, side effects, which are properly mentioned in all texts. but if an medicines is described in many disease, then it is also described to should not give in some disease/ some season or any other restrictions are mentioned very clearly. if an Ayurvedic doctor overrides the mentions, then the medicine will surely react in bad way. the central idea is "the adverse reaction of Ayurvedic medicine are doctors based not medicine based".
for example, the health tonics in Ayurveda are called RASAYANA AUSHADH. and it is very clearly mentioned in all texts that every rasayana medicine should only be given, when there is no disease or disorder lies in body. if rasayana medicines is given in presence of any disease, either the medicine will not work or it may react in bad way. CHYAWAN PRASHA is the rasayana medicine which was designed for the patients, who are depleted with disease, and the disease is treated well. so the chyawan prasha will be used after the treatment to resume the vigor, vitality in depleted person. but now days, chyawanparsha is being used to sell and purchase through out the country, without any information. which often hazardous for kidney function and intestinal health.
always use Ayurvedic medicines with the proper recommendation of well educated Ayurvedic doctor.
