There is a famous sloka in Sanskrit which reads as follows:
ayogyah purusho naasti
This can be translated as ‘there is no letter which is not a mantra, there is no root (or herb) which is not a medicine, there is no person who is not suitable (good). What is missing, often, is the person who knows to apply properly in the context
Everything and everyone in the world exist for a reason. It could be used for benefit of one another. But there should be someone which has the knowledge, experience and willingness to venture into it and help
It is equally applicable in healthcare as well. Now a days, information is available on fingertips for everyone. eg. what causes a disease, what could be the medicines/treatments etc. However, if it is not applied with the help and advice from a well qualified, experienced physician these may lead to unwanted consequences.
This is true irrespective of whether one is following allopathy, ayurveda, homeopathy etc.
