Pokok Lidah Buaya or Aloe vera is one of the best-studied medicinal plants. The clear gel inside the leaves and the yellow latex just beneath the leaf skin have different properties and uses.
Medicinal uses of Aloe vera
- Burns and minor wounds
Aloe vera gel is commonly used to:
- Soothe minor burns (including mild sunburn)
- Promote healing of superficial wounds
- Reduce pain and skin irritation
Evidence suggests it may help some superficial burns heal faster, although results vary depending on the type of wound.
- Skin conditions
Topical aloe vera gel may help relieve symptoms of:
- Dry skin
- Mild eczema
- Psoriasis (as an adjunct treatment)
- Acne (when combined with standard treatments)
- Skin irritation after shaving or insect bites
It acts as a moisturizer and has mild anti-inflammatory properties.
- Oral health
Aloe vera mouthwash or gel has been studied for:
- Reducing plaque
- Gingivitis (gum inflammation)
- Mouth ulcers (aphthous ulcers)
- Oral mucositis in some patients receiving cancer treatment
Other potential benefits
Research suggests aloe vera may have:
- Anti-inflammatory activity
- Antioxidant properties
- Antibacterial and antifungal effects against certain microorganisms
- Blood sugar-lowering effects in some people with prediabetes or type 2 diabetes
- Possible cholesterol-lowering effects, but more research is needed.
Digestive uses
Traditionally, aloe latex has been used as a strong stimulant laxative.
However:
- Aloe latex can cause abdominal cramps and diarrhea.
- Frequent or high-dose use may lead to dehydration, electrolyte imbalances (especially low potassium), and dependence on laxatives.
- Because of these risks, aloe latex is not recommended
Active compounds
The gel contains:
- Polysaccharides (especially acemannan)
- Vitamins (including vitamins C and E)
- Minerals
- Amino acids
- Enzymes
The latex contains:
- Aloin (barbaloin)
- Anthraquinones, which are responsible for its laxative effect.
Among the many traditional uses of aloe vera, the strongest scientific evidence supports:
- Relief and healing of minor burns
- Moisturizing and soothing irritated skin
- Improving some oral health conditions, such as plaque, gingivitis, and mouth ulcers
