The presence of choline helps control cholesterol, allows the liver to function properly and participates in the memorization process. Aloe vera is particularly useful in preventing or fighting constipation.

Aloe gel improves the condition of mature skin because it has biogenic stimulation properties. It multiplies, by 7 or 8, the production of fibroblasts, which create human collagen. Moisturizing and emollient, it softens irritated, surface-burnt or very dry skin.

For ingestion of the Aloe vera drinkable gel or its latex, in liquid or capsules, follow the dosage indicated on the containers. If in doubt, it is best to seek advice from your doctor or pharmacist.

The latest scientific research has focused on Aloe vera-based gels and creams and has been conducted in dermatology. Further research on the action of Aloe vera gel on gingivitis has not confirmed its effectiveness. In addition, further clinical trials have been conducted in the treatment of diabetes, genital herpes, and chronic constipation. Some results indicated that a topical product containing 0.5% Aloe vera extract was much more effective than a placebo in helping to treat lesions caused by genital herpes.
