Baptisia tinctoria
Pronounced Wild Indigo: wyld IN-dih-goh. Baptisia tinctoria: bap-TISS-ee-uh (or bap-TIZH-uh) tink-TOR-ee-uh.
Cool and drying: a small-dose, bitter, acrid antiseptic alterative and lymphagogue that clears sepsis, putrid ulceration, and swollen-gland stagnation from dusky, boggy, congested tissue.
Avoid. Baptisia root carries teratogenic and toxic quinolizidine alkaloids, notably anagyrine, the lupine alkaloid responsible for teratogenic 'crooked calf' malformations, together with cytisine, a toxic nicotinic agonist. The herb also has a traditional tissue-stimulating, emmenagogue reputation and is emeto-cathartic in more than small doses. Modern references classify Wild Indigo as unsafe in pregnancy and advise avoidance (WebMD/RxList consumer safety; AHPA Botanical Safety Handbook, 2nd ed.; Brinker, Herbal Contraindications and Drug Interactions; Mills and Bone, Principles and Practice of Phytotherapy). There is no established safe dose in pregnancy. Note: a minority teaching monograph (Southern Cross University) calls it safe in pregnancy; that view is not supported by the alkaloid toxicology and is not followed here.
Avoid; insufficient data. The toxic quinolizidine alkaloids (cytisine, anagyrine) may pass into breast milk, and there are no adequate human safety data for Wild Indigo during lactation. Given the alkaloid toxicity and the herb's emetic tendency, modern references advise against use while breastfeeding (AHPA Botanical Safety Handbook, 2nd ed.; Mills and Bone; WebMD/RxList). Prefer better-studied lymphatic and immune herbs during lactation.
Not for infants or long-term pediatric use; older children only under professional supervision at low, short-course doses. The root's quinolizidine alkaloids are toxic and the herb is emeto-cathartic in more than small amounts, so it is easy to overshoot in a child. Reserve any pediatric use to a qualified practitioner for acute, self-limited septic or glandular conditions at reduced dose. Insufficient modern pediatric safety data (Mills and Bone; WebMD/RxList).
Baptisia root contains toxic quinolizidine (lupine-type) alkaloids, chiefly cytisine (historically called baptitoxine) with N-methylcytisine and anagyrine; cytisine is a nicotinic acetylcholine-receptor agonist. Only small doses are used. In more than small therapeutic amounts the root is emeto-cathartic, causing nausea, vomiting, salivation, diarrhea, and gastroenteritis, and large overdoses can produce the nicotinic picture of quinolizidine poisoning (headache, vertigo, weakness, cramping, and in extreme excess convulsions and respiratory depression). It is a short-course acute remedy, not a long-term tonic. Anagyrine is a known teratogen (the lupine 'crooked calf' teratogen), which underlies the pregnancy contraindication. As an immune stimulant it warrants caution in autoimmune disease and with immunosuppressive therapy (see Drug Interactions).
Pregnancy (teratogenic and toxic quinolizidine alkaloids; see safety fields). Lactation (toxic alkaloids, no safety data). Large or prolonged dosing (emeto-cathartic; alkaloid toxicity). Autoimmune disease and organ transplantation, or concurrent immunosuppressant therapy, because of the immune-stimulating fraction (theoretical, by analogy to other immunostimulant herbs). Known easy nausea or sensitivity, given the herb's emetic tendency.
Baptisia tinctoria is a native eastern North American perennial legume and is not presently listed as at-risk or to-watch by United Plant Savers. It is nitrogen-fixing and readily cultivated, but harvesting the root kills the plant and wild digging of native stands is destructive, so prefer cultivated, organically grown root and leave wild colonies (which also support native pollinators and the wild indigo duskywing butterfly) intact.
Not in canonical biblical texts, and unknown to the ancient Mediterranean world; native to eastern North America. Its documented tradition is Native American (used by the Mohegan, Cherokee, and others for infected wounds, sore mouth, and glandular swellings) and, from the nineteenth century, Eclectic and Physiomedical American herbalism, where it became a signature antiseptic for septic, ulcerative, and typhoid states.
