- Eugenol overdose: Excessive consumption of basil leaves can lead to Eugenol overdose, which is a key element in Tulsi. Symptoms include bleeding during coughs, rapid breathing, and blood in the urine.
- Blood thinning: Tulsi has the ability to avoid thickening of blood in the body. However, if consumed excessively it can lead to extreme blood thinning. To avoid this, you must not consume too much basil leaves if you’re already on anti-clogging or blood-thinning medications.
- Hypoglycemia: Tulsi can reduce blood sugar levels drastically and therefore must not be consumed in excess to avoid hypoglycemia, a condition that causes one to have abnormally low blood sugar levels.
- Allergies and pregnancy: If you are allergic to basil, you must avoid the use of basil leaves altogether. Basil can also have long-term effects on pregnant women and the baby such as complications during childbirth or menstruation. One of the side effects of basil also includes an increase in uterine contractions in pregnant women.
