As we all know popular Nestle brand Maggi was banned because it contains Monosodium Glutamine and Lead of 17 ppm whereas Lead of up to 0.01 ppm is permissible. Ayurvedic medicines are proved to have heavy lead which is dangerous to human instead of being curing agents.

Ayurvedic text explaining to add lead heavy metal to medicine ‘Pushpadhanwa Rasa’.
हरभुजगलय्हं चाभ्रकं वंगचूर्ण कनकविजययष्टी शाल्मली नागवल्ली।
घृतमधुसितदुग्धं पुष्प धन्वा रसेन्द्रो रमयति शतरामा दीर्घमायुर्बलंच॥

Some of the common myths, apologist argument justifying Lead metal in Ayurveda
1) Lead in Ayurveda is different or processed and because of that it will not cause harm.
This is completely absurd. Any form of Lead metal is poisonous to body and there is no safe Lead.
2) Ayurveda, Siddha, Unani are practised for 1000 years. If that is the case, how come it is possible to have harmful metal in it?
While it is true that some Ayurvedic-Siddha medicines might have benefits, none of these health benefits have been recorded by systematic study involving multiple field trials and randomized control tests. Did any time Ayurveda-Siddha went thru scrutiny for their effectiveness. If they were effective why was life expectancy of Indians was far less before advent of modern medicine ? Indian union govt should ask its AYUSH (Ayurveda, Yoga, Unani, Siddha, Homoeopathy) department to carry out this independent study before allowing these products in market. Instead these products are blindly sold to vulnerable patients who are already in weak position because of disease.
Just because Homeopathy was invented by a German, people in Germany are not rallying for it or defending it. Every medical school should be evaluated by its merit and ability to cure diseases not by its origins. Innocent peoples life is not a place where one can show his/her patriotism. Doing so will be just chauvinism.
