2.4. May Help Prevent Cancer
Some studies indicate that bay leaves may help inhibit the growth of breast and colorectal cancer cells. However, these findings are preliminary and not yet conclusive, necessitating further research in humans to confirm this effect of bay leaves.
Additionally, according to the Journal of Nutritional Research, the combination of antioxidants and organic compounds in bay leaves, including phytonutrients, catechin, linalool, and parthenolide, helps protect your body from the effects of cancer-causing free radicals.
2.5. May Prevent Kidney Stones

Urease is an enzyme that, when imbalanced, can lead to various gastric disorders, including kidney stones.
Much like the research on cancer prevention, studies on bay leaves for preventing kidney stones also require further investigation to draw accurate conclusions.

Moreover, bay leaves can affect the central nervous system (CNS) when combined with anesthetics and other medications used during and after surgery. Hence, you should discontinue use at least 2 weeks before surgery or consult your doctor.
