S. Ghosal et al., INTERACTION OF SHILAJIT WITH BIOGENIC FREE-RADICALS, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 34(7), 1995, pp. 596-602
Processed shilajit (PS), consisting of resonance stabilized soft-spin
semiquinone free radicals, has been shown to produce free radical scav
anging and antioxidant effects against SO3- and OH radicals and the pa
ramagnetic nitric oxide (NO) depending on the concentration of PS. Age
nts that can regulate uncontrolled production and function of such bio
genic free radicals would conceivably provide cellular protection and
revitalization to recipients. The results obtained in this study offer
a suitable rationale for the rasayan (revitalizer) effects of shilaji
t as claimed in Ayurveda.
