Toxic (Pb, Cd,Hg, Pd andCr) aswell as essential (Zn,Mn,Ni, Co,Cu and Fe) heavy metals in different types of Allopathic (Paracetamol and Citrazine hydrochloride), Ayuurvedic (Mruthyunjaya Ras and Shwaskuthar Ras), Unani (Habb-eMubarak, Qurs-e Nazla and Habe-Surfa) and Homeopathic (Bryonia-200 andAlliumCepa-200)medicine commonly used against cold and fever were determined by atomic absorption spectrometry (AAS).
