Identity & plant part
A tall, often single-stemmed aloe with thick, spiny leaves and a conspicuous flowering head. The Cape aloe is a southern African species. Do not substitute another aloe on the basis of appearance or the common name alone. [Sources]
Traditional knowledge
SANBI records a long medicinal history. Aloe products may use the inner leaf material for skin preparations or the bitter exudate for a very different purpose. A label saying only “aloe extract” does not identify which material is present. [Sources]
How the medicine is extracted
Processors separate the clear inner leaf material from the yellow-brown exudate associated with the outer leaf tissues. Gel preparations require controlled handling and microbial quality checks. Bitter exudate can be collected and concentrated separately. Mixing the two changes the chemical and safety profile; this is not a home preparation guide. [Sources]
Scientific evidence & limitations
The botanical account documents use rather than proving that all aloe products treat disease. Anthranoid-containing bitter preparations are distinct from gel cosmetics. Evidence for one preparation cannot be transferred to a whole-leaf juice, another species, or an Enki product. [Sources]
Safety & suitability
Do not drink fresh whole-leaf preparations or assume a skin gel is edible. Bitter aloe preparations can cause diarrhoea and fluid loss. Ask a pharmacist about pregnancy, children and medicine interactions. [Sources]
Conservation & knowledge holders
Use correctly identified, traceable cultivated material; indiscriminate leaf harvesting can damage plants. [Sources]
