I am not against Ayurveda but I would like to say some thing.
Ayurvedic medicines were effective at the time of Charak, but hundreds of years have passed and all atmosphere and time has changed so now these medicines are working or not,we do not know.
In old time as per example Serpina was given for hypertension
but now a days how many Ayurvedic people (I will call Vaidraj and not doctors) know about this ? It is completely abolished from the list as it has got impotence
So what i am of opinion that medicine working at the time of Charak now will be useless and so now ayurvedic medicine require research and statistic so that people know about and use of it.
Previously people thought that ayurvedic medicines were cheap but now as you all know the price.
the name of articles you mentioned, used in various conditions,we should find out the active ingredients from these articles and we should separate and remaining should be removed so that side effects of the medicines can be minimize.
