Lemons (Citrus limon) belong to the citrus family, along with oranges, limes, and pomelos. Like other citrus fruits, they’re rich in natural oils that give off a fresh, fragrant scent when the peel is crushed. The main compound behind that aroma is limonene, which has been studied for potential health benefits.

LIMONENE: MORE THAN A FRAGRANCE
Limonene is the largest component of oil extracted from citrus peels. Beyond its use in soaps, air fresheners, and food flavorings, research suggests it may have health-promoting effects:
- Anti-cancer potential: Early studies show limonene may help kill certain cancer cells and protect against breast, colorectal, and lung cancers.
- Liver and metabolism support: Animal studies suggest limonene can reduce fatty liver and improve insulin resistance, a key factor in diabetes.
- Weight control: Some studies link citrus extracts to reduced weight gain in lab animals.
- Anti-inflammatory effects: Limonene acts as an antioxidant and may reduce inflammation in the body.
- Relaxation and sleep: In aromatherapy, citrus oils can reduce anxiety and support better sleep.
While promising, these findings are still being researched. More human studies are needed before firm conclusions can be made.
VITAMIN C: BOOST HEALING AND DEFENCE
Lemons are also well known for their vitamin C content. Vitamin C is important for:
- Building collagen, the protein that supports skin, cartilage, and blood vessels
- Wound healing
- Helping the body absorb iron
- Supporting the immune system
Although vitamin C won’t “cure” the common cold, studies show it may help reduce the severity and complications of infections.
A Note of Caution
While lemons and citrus oils offer health benefits, they should be seen as complements, not substitutes, for medical treatment. Always let your doctor know if you plan to use natural remedies alongside prescribed medication.
