Comparative immunomodulation potential of Tinospora cordifolia (Willd.) Miers ex Hook. F., Tinospora sinensis (Lour.) Merrill and Tinospora cordifolia growing on Azadirachta indica A. Juss.

Guduchi has been widely used in the traditional medicine as an immunomodulator. Description of guduchi in Ayurvedic literature resemble with T. sinensis rather than with commonly available T. cordifolia and hence this may be used as substitutes for T. sinensis. T. cordifolia growing on Azadirachta indica commonly called Neem-guduchi has more immunomodulatory potential. Thus, immunomodulatory activity of three Tinospora spp. was assessed by checking humoral and cell mediated immune responses to the antigenic challenges with sheep RBCs and by neutrophil adhesion tests on albino Wistar rats using Guduchi-Satwa, a well known dosage form. Results revealed that Neem-guduchi possesses higher immunomodulatory potential at the dose of 300 mg/kg, po and validated the traditional claim. Hence, Neem-Guduchi can be employed in immunomodulatory formulation prepared using guduchi.
