When thirty different varieties of legumes were studied for their antioxidant activity and phenolic content using different tests, Horse gram was found to be one of them showing high DPPH free radical scavenging activity (9).

In another study it was revealed that administration of Horse gram to rabbits induced with high fat diet had shown a significant decline in thiobarbituric acid reactive substance (TBARS) levels, showing the signs of antioxidant nature of the horse gram.

In addition to that, the GSH levels were also enhanced. GSH is also known as glutathione is a major antioxidant capable of fighting against free radicals and also act as a detoxification agent.
