Bioavailability of the well-known Ayurvedic drug Swarnabhasma (gold bhasma or calcined gold) is unknown. It is orally administered either sublingually or directly with various Anupanas like black pepper powder (Piper nigrum Linn.) and cow ghee in the dose range of 15–240 mg by Ayurvedic physicians. Study of bioavailability of Swarnabhasma is necessary as this metal-derived drug is administered for long duration for rejuvenation. The pilot study was carried out in healthy human male participants to assess bioavailability of Swarnabhasma in three doses, viz. 30 mg plain sublingual, 30 mg oral dose mixed with black pepper powder (250 mg) and cow ghee (2.5 gm); and 240 mg oral dose mixed with black pepper powder (250 mg) and cow ghee (2.5 gm). Blood samples were withdrawn at 0, 1, 2 and 4 h after administration of dose. Estimation of gold levels in blood was carried out by inductively coupled plasma mass spectrometry (ICP-MS). Results show that gold is absorbed in traces from single dose of Swarnabhasma. Maximum concentration of gold was bioavailable from 30 mg sublingual dose with Cₘₐₓ 0.983 μg/L at 2 h (Tₘₐₓ). Oral dose of 30 mg Swarnabhasma mixed with black pepper powder and ghee showed faster absorption with Tₘₐₓ at 1 h and Cₘₐₓ 0.867 μg/L, and 240 mg dose with black pepper and ghee showed Cₘₐₓ 0.668 μg/L and Tₘₐₓ at 2 h.
