Allium cepa (Onion) is indicated for which of the following conditions?

• A. Digestive ulcers
• B. Sleep disorders
• C. Cardiovascular health
• D. Eye disease

Answer: (C)

The main idea here is that Allium cepa has properties that support the cardiovascular system. Onions contain sulfur compounds and flavonoids (like quercetin) that act as antioxidants and help protect blood vessels. They can promote vasodilation, support healthy lipid levels, and aid in reducing oxidative stress in the circulatory system. These actions translate into traditional use for cardiovascular health, making it the most appropriate indication among the options.

Digestive ulcers don’t fit well because onions can be irritating to the GI tract and aren’t a demulcent or ulcer-healing herb. Sleep disorders aren’t addressed by onion’s pharmacology, which lacks sedative or hypnotic effects. Eye disease isn’t supported by onion’s typical uses; while cutting onions can cause tearing, that’s a physiological reaction, not a therapeutic indication for eye disease.
