Aloe ferox
Also known as Bitter Aloes
Pronounced Cape AL-ohz (BIT-er AL-ohz); AL-oh-ee FEH-roks
Cool, dry, intensely bitter: the drastic stimulant purgative that rouses a torpid, congested colon, drains Liver fire downward, and unblocks suppressed menses. A short-term drainer, never a daily tonic.
No pre-1900 source found for this exact plant. The old books describe aloes from other species, not the South African plant this entry is about.
Contraindicated. Aloe latex is an anthranoid stimulant laxative and traditional emmenagogue; oral use can provoke reflex uterine stimulation and pelvic congestion and is judged possibly unsafe in pregnancy. Do not use. (NCCIH 'Aloe Vera'; AHPA Botanical Safety Handbook 2nd ed., leaf-latex class 2b (not verified against AHPA); King's 1898, which forbids it in pregnancy.)
Contraindicated (EMA/HMPC). Anthraquinone metabolites (aloe-emodin and related aglycones) are excreted into breast milk and may purge or gripe the nursing infant; the EMA/HMPC monograph contraindicates use during breastfeeding. King's likewise notes the purgative principle passes into the milk. (NCCIH; AHPA Botanical Safety Handbook 2nd ed.)
Contraindicated under 12 years. Oral aloe latex and whole-leaf extracts are possibly unsafe in children and can cause abdominal pain, cramps, and diarrhea with fluid and electrolyte loss. Stimulant laxatives are not appropriate for pediatric constipation. (WebMD/Natural Medicines; NCCIH.)
A drastic anthranoid stimulant laxative for short-term use only (EMA/HMPC: no longer than 1 week). Habitual use causes laxative dependency, loss of colonic tone, potassium loss, and melanosis coli. Always combine with a carminative (fennel, ginger) to blunt the intestinal griping. Reserve the concentrated latex for stubborn constipation after gentler bulk and osmotic measures fail. This is the bitter latex, not the soothing inner-leaf gel.
Absolute: pregnancy; intestinal obstruction or ileus; acute inflammatory bowel disease (Crohn's, ulcerative colitis); appendicitis or undiagnosed acute abdominal pain; children under 12. Relative: hemorrhoids and anal fissures (aggravates piles), existing hypokalemia, and concurrent potassium-depleting drugs.
Aloe ferox is listed on CITES Appendix II (international trade in leaves and derivatives requires permits; seeds and cut flowers of artificially propagated plants are exempt). It is assessed Least Concern in South Africa, where a Biodiversity Management Plan and a 2018 non-detriment finding judged the wild leaf-tapping trade low to moderate risk. Leaves are tapped from wild stands without killing the plant, which regrows, but localized over-harvesting and destructive tapping by untrained harvesters occur in the Eastern Cape. Prefer certified, sustainably tapped Cape aloe from managed South African supply chains.
Aloes appear at the burial of Jesus: 'And there came also Nicodemus ... and brought a mixture of myrrh and aloes, about an hundred pound weight' (John 19:39, KJV); fragrant 'aloes' also occur in Psalm 45:8, Proverbs 7:17, and Song of Solomon 4:14, and 'lign aloes' in Numbers 24:6. Scholarship is divided: the Old Testament ahalim / ahaloth (lign-aloes) is most likely fragrant agarwood (Aquilaria), and the John 19:39 aloes may have been either true Aloe or aromatic aloeswood used for embalming and perfume. The medicinal purgative Cape aloes (Aloe ferox) is a South African species not native to the biblical Levant; it is grouped here for its shared common name and its historic role as the source of officinal bitter aloes.
