A review of 15 studies involving 344,488 participants indicated that consuming an average of 10 grams of flavonoids per day could reduce the risk of heart disease by 5%.

A study on obese mice found that D-limonene helped lower blood sugar, triglyceride levels, and LDL (bad) cholesterol while increasing HDL (good) cholesterol.

Another study conducted over four weeks on 60 overweight children showed that consuming lemon powder (which includes lemon peel) helped lower blood pressure and reduce bad cholesterol levels.

Additionally, pectin in lemon peel helps lower cholesterol by increasing bile acid secretion and binding to cholesterol.
3. Aids in Gallstone Treatment
Some studies suggest that D-limonene may help treat gallstones.

In a study of 200 patients with gallstones, 48% of participants who received D-limonene injections saw complete dissolution of their stones. This suggests that D-limonene could be a potential alternative to surgery. However, further research is needed to confirm whether D-limonene from lemon peel can effectively dissolve gallstones.

4. Antibacterial and Antifungal Properties
Lemon peel contains compounds with antibacterial and antifungal properties.

Laboratory studies have shown that lemon peel can significantly inhibit the growth of antibiotic-resistant bacteria. Another study found that lemon peel extract was effective against drug-resistant fungi that cause skin infections.

These findings provide promising evidence of lemon peel’s potential health benefits. However, more research is required to confirm its effects on the human body.
5. Lowers Blo.od Fat Levels
Lemon peel helps reduce blood fat levels, lower cholesterol, and prevent fatty liver disease, high blo.od pressure, and cardiovascular diseases.

Precautions When Using Lemon Peel
Before using, thoroughly scrub lemon peel with baking soda, salt, or fruit-washing solutions to remove any harmful residues.
Avoid consuming too much lemon peel, as its strong flavor can be overwhelming and unpleasant. When used as a medicinal ingredient, the recommended intake should not exceed 20 grams per day.
If you drink lemon peel water and do not urinate within two hours or experience headaches, stop consumption immediately. Proper use should promote frequent urination within two hours.
Consult a doctor before using lemon peel water, especially if you have a history of chronic illnesses or other health concerns.
