Plantago ovata
Pronounced Psyllium: SIL-ee-um (the p is silent). Plantago ovata: plan-TAY-go oh-VAH-tah.
Cool, moist, and soothing: a bland mucilage that bulks, softens, and calms the bowel, gliding stagnation out and firming looseness in, without heat or gripe.
Considered safe. Psyllium is not absorbed systemically, and bulk-forming laxatives including psyllium are recommended as a first-line option for constipation in pregnancy when diet and fluids are insufficient. Take each dose with a full glass of water. Sources: AHPA Botanical Safety Handbook, 2nd ed. (safety class 1 (not verified against AHPA)); MotherToBaby (OTIS) Laxatives fact sheet; Mayo Clinic; NCCIH.
Considered compatible. Because psyllium is not absorbed from the gastrointestinal tract, it does not enter breast milk and is regarded as a safe choice for postpartum and lactational constipation. Sources: AHPA Botanical Safety Handbook, 2nd ed. (safety class 1 (not verified against AHPA)); NIH Drugs and Lactation Database (LactMed); NCCIH.
Used in children for constipation at reduced, age-appropriate doses, provided the child reliably drinks adequate fluid with each dose to prevent choking or obstruction. Avoid in a child who cannot swallow it with enough liquid. Sources: NCCIH; AHPA Botanical Safety Handbook, 2nd ed. (safety class 1 (not verified against AHPA)); standard pediatric bulk-laxative practice.
Must always be taken with abundant fluid (a full glass of water per dose plus a second glass): taken dry or with too little liquid it can swell in the throat or gut and cause choking, esophageal blockage, or bowel obstruction. Start low and increase gradually; abrupt high doses commonly cause bloating, flatulence, and cramping as the gut flora adjust. May transiently reduce the absorption of minerals and of medicines taken at the same time. Rare but real IgE-mediated allergy (rhinitis, asthma, urticaria, anaphylaxis) occurs, most often in healthcare and pharmaceutical workers with repeated dust exposure and occasionally on ingestion.
Do not use with any known or suspected gastrointestinal obstruction, ileus, fecal impaction, esophageal stricture or narrowing, or difficulty swallowing (dysphagia). Avoid in acute, undiagnosed abdominal pain and in known psyllium hypersensitivity. Not to be taken immediately before lying down or by anyone who cannot reliably drink enough fluid with each dose.
Not at risk. Plantago ovata is a widely cultivated annual field crop, grown at large scale in northwest India (especially Gujarat) and elsewhere, and is not listed by United Plant Savers or any conservation body. Prefer certified, cleanly processed cultivated husk; the main sourcing concerns are purity, low dust exposure for handlers (occupational allergen), and freedom from adulteration rather than wild-harvest pressure.
Not named in canonical biblical texts. The genus Plantago and the flea-seed psylliums were, however, well known to the ancient Mediterranean: Dioscorides describes psyllion (the flea-wort, Plantago psyllium / P. afra) as a cooling, soothing seed in De Materia Medica, and Pliny records similar use. Plantago ovata itself is native to the Mediterranean basin, North Africa, and West and South Asia and is a cornerstone of Unani and Ayurvedic practice as isabgol, the classic cooling demulcent regulator of the bowel.
