Cape Aloe
Aloe ferox
Long before it reached European apothecary shelves, Cape Aloe was gathered by the Khoisan peoples of southern Africa, who understood the plant's two very different gifts: a cool, mucilaginous gel prized for the skin, and a bitter yellow sap prized as medicine. By the early 1700s, Dutch and British traders were exporting the dried, crystallized sap from Cape Town as one of South Africa's first great herbal commodities, known simply as Cape Aloes, and it became a staple bittering agent in tonics and pharmacy compounds across Europe. Farmers still tap the leaves by hand today, much as their grandparents did, letting the sap bleed into trenches cut around a drum of standing leaves.
In tradition.

Traditional preparations.
The clear, mucilaginous gel from a freshly cut leaf has traditionally been smoothed over minor sunburn, dry skin, and small kitchen burns to cool and soothe.
Slice a mature leaf lengthwise and scoop out about a tablespoon of the clear inner gel, avoiding the yellow sap layer just under the skin. Apply directly to clean, unbroken skin and let it absorb; refrigerate any leftover gel and use within two or three days.
In small, occasional amounts, the dried bitter sap has traditionally been dissolved in warm water as a digestive bitter to encourage regularity.
Traditionally, a pinch, no more than what would fit on a fingertip, of the dried bitter extract is dissolved in a cup of warm water and taken occasionally, not as a daily habit. This preparation is strongly laxative even in small amounts, so it calls for real caution and is best approached only under guidance from a qualified herbalist or healthcare provider.
Safety.
The bitter latex beneath Cape aloe's leaf skin is a strong laxative that can cause cramping, diarrhea, and electrolyte loss if overused, and it should never be taken during pregnancy or by children. It isn't appropriate for anyone with intestinal obstruction or inflammatory bowel conditions, and may interact with heart or diuretic medications. The clear inner gel is gentler for use on unbroken skin, but patch test first.
