Aloe Vera Inner Leaf Gel Aqueous Extract
Also known as: Aloe vera, Aloe, Aloe vera gel, *Aloe barbadensis*
Overview
Aloe vera, also known as *Aloe barbadensis*, is a succulent plant whose inner leaf gel is widely used for its beneficial medicinal and cosmetic properties. The gel consists of approximately 99% water, with the remainder being composed of various bioactive compounds such as polysaccharides, amino acids, vitamins, and phenolic compounds. Key applications of Aloe vera encompass wound healing, treatment of skin ailments, and relief for gastrointestinal disorders. Known for its anti-inflammatory, antioxidant, and immunomodulatory characteristics, Aloe vera has a moderate research maturity level. Evidence supporting its efficacy is growing, though often limited by small sample sizes and varying methodological rigor.
Benefits
Aloe vera gel exhibits several significant benefits, primarily in wound healing and gastrointestinal conditions. Evidence suggests that it enhances wound healing by promoting the proliferation of fibroblasts and keratinocytes. A noteworthy meta-analysis indicated significant improvement in symptoms of Irritable Bowel Syndrome (IBS), with a standard mean difference (SMD) of 0.41 (95% CI, 0.07–0.75). Its anti-inflammatory and antioxidant activities are also noteworthy, potentially aiding in various health issues, particularly for individuals with constipation-predominant IBS. While benefits are observed primarily in short-term applications, clinical significance can vary based on individual responses.
How it works
Aloe vera's beneficial effects are largely attributed to its polysaccharides—especially acetylated mannans—which exert immunomodulatory effects. Additionally, anthraquinones in Aloe contribute to its laxative properties. The extract influences multiple body systems, including skin, gastrointestinal, and immune systems, although specific molecular targets and absorption rates remain inadequately defined in current research.
Side effects
Aloe vera is generally regarded as safe for short-term use, although long-term safety is not well established. Common side effects, occurring in more than 5% of users, include gastrointestinal upset when taken orally. Less frequent adverse reactions, affecting 1-5% of users, comprise allergic reactions and skin irritation. Rare side effects are not extensively documented. Caution is advised for individuals taking diabetes medications due to potential interactions. Pregnant and breastfeeding populations should avoid its use due to insufficient safety data. Those with diabetes or on related meds should also approach use with caution.
Dosage
Recommended dosages for Aloe vera vary based on the application method, with no well-established minimum effective dose. For topical applications, the gel form is typically used as needed, while oral dosages can differ significantly among formulations. Although there is no clearly defined maximum safe dose, practitioners advise caution with high doses. Topical applications should be performed as necessary, while oral use is usually recommended before meals. Due to inadequate data, specific absorption factors and co-factors required for optimal effectiveness have not been identified.
FAQs
How should I use Aloe vera gel?
