 1. Cardiac Activity: Research on rats indicates that Holy Basil extracts have positive effects on heart health. In stressed rats, the extract prevents stress-induced changes in the heart. Additionally, feeding rats with O. sanctum L. inhibits isoproterenol-induced alterations in enzyme activities. Different doses of O. sanctum L. extract also show significant reduction in markers of heart damage in rats with induced myocardial infarction. The study suggests potential cardioprotective effects. 3 4 

2. Wound Healing: Tulsi may help wounds heal faster by making them stronger and forming new tissue. For unusual healing situations like keloids and hypertrophic scars, Tulsi supports effective wound contraction shown in an animal study. Even when healing is slowed by dexamethasone, Tulsi shows promise in overcoming medication challenges. It’s a natural friend in helping the body heal better. 3  

3. Genotoxicity: Tulsi, with its leaf extract, can help fight against harmful effects caused by heavy metals like chromium and mercury. In animal trails, Ocimum sanctum leaf extract supports recovery, helps restore the cell division process, and reduces changes in our chromosomes. Tulsi’s ability to protect against genetic damage from environmental factors makes it a natural helper, especially in smaller amounts. 3  

4. Antioxidant: Tulsi may possess remarkable stress-fighting abilities due to its antioxidants found in essential oils and water extracts. These antioxidants play a crucial role in safeguarding our cells by enhancing the activity of key antioxidant enzymes.
