In addition, aloe vera has been shown to accelerate wound healing in periodontal flap surgery [1].

Gastroesophageal reflux disease, also known as acid reflux is a condition which occurs when the stomach acid flows back into the oesophagus. Aloe vera has been shown to have the ability to lower the symptoms of gastroesophageal reflux disease (GERD) which includes heartburn, vomiting and belching [5].

Another benefit of aloe vera is it can help in curing sunburn. Due to the cooling and antioxidant properties in aloe vera, it is used as a remedy for relieving sunburn. Also, aloe vera gel acts as a shield against radiation damage on the skin.


8. Keeps the skin good

Aloe vera aids in the production of collagen and elastin fibres that make the skin more tight and prevents wrinkles. The amino acids and other nutrients in aloe vera soften hardened skin cells and act as an astringent to tighten skin pores. This improves skin health and decreases the appearance of wrinkles.


9. Enhances hair health

Aloe vera is an excellent choice for promoting hair growth naturally and stopping hair fall. The anti-inflammatory and anti-bacterial properties can effectively treat hair problems like dandruff, premature hair loss, and scalp inflammation.

Pregnant women and breastfeeding mothers should avoid consuming aloe vera because it will stimulate uterine contractions in pregnant women and may cause gastrointestinal problems in nursing infants [1].
