Cons of Tulsi leaves-

1. Women who are pregnant or trying to get pregnant should not take tulsi as it may affect reproductive capacity, possibly due to its ursolic acid content. Also, Tulsi may increase testosterone levels.

2.Tulsi contains eugenol, if taken in greater amounts, it may cause liver damage.
