Herb comparison
Aloe (Aloe vera) vs Tea Tree (Melaleuca alternifolia)
Both plants are listed as traditional remedies for 2 of the same conditions, which is why they are easy to confuse. Their descriptions and full safety notes are below, free.
Tea Tree (Melaleuca alternifolia) is restricted
Preparation amounts are not shown for this herb. It is toxic, restricted, or otherwise unsafe to self-dose - the margin between a traditional dose and a harmful one is too small to publish as reference material. If you are considering it, that conversation belongs with a doctor or a qualified practitioner, not a website.
- About
- Aloe vera (syn. A. barbadensis) is a succulent commonly grown as a potted plant, notable for its thick, fleshy leaves that contain two distinct medicinal components. Historically, the inner clear gel was used for skin conditions and to promote wound healing (NCCIH), while the bitter yellow sap from the leaf base, often called “bitter aloes,” is a strong laxative.Tea tree (Melaleuca alternifolia) is a small evergreen native to Australia, with papery bark, narrow leaves, and white to cream flower spikes. Its leaves yield a pungent essential oil; the Aboriginal people of Australia traditionally used the leaves for wounds, burns, and insect bites, and NCCIH says a small amount of evidence suggests the oil, applied to the skin, might help acne and athlete’s foot.
- Safety & precautions
- The outer leaf sap contains anthraquinone glycosides (like aloin) that act as a strong stimulant laxative; NCCIH notes that in 2002 the FDA required aloe latex to be removed from over-the-counter laxative products because of a lack of safety data. Liver: Oral aloe leaf extracts have been tied to cases of acute hepatitis (NCCIH), and LiverTox rates oral aloe a likely but rare cause of liver injury. Pregnancy: NCCIH says aloe gel, latex, or whole leaf extract taken by mouth may be unsafe during pregnancy and while breastfeeding. Some herbalists advise that children and older adults not drink aloe juice containing the strong laxative compounds. Avoid internal use if suffering from kidney disease or hemorrhoids. Concentrated or unfiltered products (containing the outer rind) can be irritating.Essential Oil (Internal Use): Potentially toxic; NCCIH says tea tree oil should not be swallowed. Allergic Reaction: Rare but possible. Dilute before applying topically to sensitive skin.
