Side effects of tulsi Leaves  

Affects male and female fertility

In a study conducted on animals, published in the International Journal of Ayurveda Research, 2010, it was discovered that tulsi could lower sperm motility and count in animals when consumed in large quantities. 

It is wise for males with infertility issues to prevent this negative effect by lowering the consumption of the herb, even though the same has not yet been proven in people. 

 Damages liver 

 Eugenol is a substance present in tulsi. Eugenol can protect the liver from damage due to toxins, but excessive amounts can harm the liver and result in vomiting, diarrhoea, a rapid heartbeat and convulsions.

Lowers blood sugar

Tulsi is known to reduce blood sugar levels. However, if a person is currently taking Diabetes medication, consuming tulsi leaves could increase the effect and cause the sugar level to drop too low.

 Harmful to those on blood-thinning medicines 

 Blood thinning is a known side effect of the tulsi plant. Tulsi is an excellent alternative for people who choose not to take blood thinning medication. However, consuming tulsi while already on blood thinners may have a negative impact on a person’s health. People who use anti-clotting medicine should avoid basil leaf consumption.


 Tulsi leaves can have an impact on the health of a pregnant woman and her unborn child. In extreme circumstances, it may even result in miscarriage. The herb may lead to potentially harmful uterine contractions.

Tulsi leaves could increase blood flow to the pelvis and uterus, which might lead to contractions. Nevertheless, there isn’t enough data to support or refute the usage of tulsi during pregnancy. To be on the safe side, specialists advise women to cease consuming tulsi.


A clinical study noted temporary moderate nausea as a side effect of tulsi use. The 13-week trial was short on unfavourable consequences, but this does not rule out the possibility of long-term side effects. 

Nevertheless, the traditional history of tulsi use suggests that any significant long-term effects are uncommon and that daily ingestion may be safe. However, this has to be confirmed by additional research.

Damages tooth enamel 

It’s likely for someone to advise swallowing tulsi leaves rather than chewing them. The same has a scientific justification. Tulsi leaves shouldn’t be chewed since they contain mercury, which harms the enamel.

Tulsi contains mercury, which when chewed, releases in the mouth and damages and discolours the teeth. Additionally, tulsi leaves are acidic by nature, but the mouth is alkaline, which can hasten the deterioration of the tooth enamel. 

To prevent tooth discolouration, one should just swallow them down.
