Sanguisorba officinalis
Pronounced Great Burnet: GRAYT BUR-nit. Sanguisorba officinalis: sang-gwih-SOR-buh oh-fiss-ih-NAY-liss. Di Yu: dee yoo.
Cold and drying: a bitter, sour, astringent root that cools reckless hot blood, staunches bleeding, and tightens lax, weeping, ulcerated tissue in the hot, damp-heat lower bowel and skin.
Avoid therapeutic (especially internal) doses in pregnancy unless supervised by a qualified practitioner. There is no reliable human safety data for Great Burnet in pregnancy: the WebMD ingredient monograph for Greater Burnet advises that there is not enough reliable information to know if it is safe and to stay on the safe side and avoid use, and standard Chinese materia medica practice treats blood-cooling, astringent hemostatics cautiously in pregnancy. It is not a documented abortifacient, but its cold, astringent nature and the absence of established safety data make avoidance of medicinal doses the prudent, consumer-safe course.

Insufficient data; avoid therapeutic doses during lactation without professional guidance. It is not known whether Great Burnet's tannins and saponins pass into breast milk or affect a nursing infant, and the WebMD Greater Burnet monograph advises avoiding use for lack of reliable safety information. Incidental culinary or topical exposure to a small area is of low concern, but concentrated internal doses should await better data or qualified supervision.

Localized topical use of the root for minor burns, sores, and weeping skin is traditional and generally gentle, but internal therapeutic dosing in children should be undertaken only under professional guidance, with no established pediatric self-dosing range. The large-burn caution applies with particular force to small children: never dress an extensive burn with tannin-rich burnet preparations, since a burn covers a proportionally larger share of a child's body surface and systemic tannin absorption raises the risk of toxic hepatitis. Any significant burn or bleeding in a child is a matter for medical care, not self-treatment. (Source: Chen & Chen, Chinese Medical Herbology and Pharmacology, Di Yu.)
Great Burnet root taken internally at ordinary doses has a long record of safe use and low toxicity, and modern studies of the root report no significant toxicity. The main cautions are three. First, timing in dysentery: because it is strongly astringent, it should not be given in the very early stage of damp-heat dysentery, when the pathogenic damp-heat still needs to be expelled, lest the astringency trap the pathogen. Second, and most important, extensive topical use on burns: although the powdered or ointment root is a classic dressing for burns and scalds, it must not be applied over large burn surfaces (roughly a third of the body or more), because its high tannin content can be absorbed through the damaged skin and cause toxic hepatitis. Third, constitutional fit: as a cold, drying astringent it is wrong for bleeding and diarrhea of the cold, deficient type and can chill and dry an already cold, depleted, or dry person. Being very tannin-rich, large internal doses may cause digestive upset or nausea and can hinder the absorption of iron and other nutrients and drugs taken at the same time.
Bleeding or diarrhea of the deficiency-cold type (Spleen or Kidney yang deficiency, interior cold), in which a cold, bitter astringent is inappropriate. The early acute stage of damp-heat dysentery, before the damp-heat is cleared. Extensive burns: do not apply topically over large areas of the body (approximately 30 percent body surface or more) because of systemic tannin absorption and hepatotoxic risk; reserve topical use for localized burns. Marked dryness, atrophy, or fluid depletion, which its drying astringency worsens. Pregnancy and lactation at therapeutic doses without professional supervision (insufficient safety data). Known hypersensitivity to the herb.
Sanguisorba officinalis is widespread across temperate Eurasia and is not listed as at-risk by United Plant Savers; it is also widely grown as a hardy garden ornamental, so cultivated root is readily and sustainably obtained and should be preferred for medicine. Note that in parts of its native range wild Great Burnet is a locally declining wet-meadow plant and the obligate host of rare large blue (Phengaris) butterflies, so wild stands carry real ecological value: favor cultivated material and do not dig wild roots from sensitive or protected meadow habitats.
Not named in the canonical biblical texts nor in the classical Greco-Roman herbals under this identity; Great Burnet is a plant of temperate European and Asian tradition, not of the ancient Holy Land flora. Its European standing as a wound and hemorrhage herb is preserved in the genus name Sanguisorba (Latin sanguis, blood, and sorbere, to staunch). In East Asia the root, Di Yu, is a long-established herb of the Chinese materia medica for cooling the blood and stopping bleeding, within the tradition reaching back to the Shennong Ben Cao Jing. Cited honestly as a herb of European folk medicine and Chinese medical tradition rather than of Scripture.
