Ruscus aculeatus
Also known as Knee Holly, Jew's Myrtle
Pronounced Butcher's Broom: BUUCH-erz broom. Ruscus aculeatus: RUSS-kus ah-kew-lee-AY-tus.
Cool and drying: an astringent venous tonic that tightens lax, dilated veins, decongests venous pooling and edema, and cools inflamed, boggy hemorrhoidal and varicose tissue.
On temperature, Gerard (1633) and Culpeper (1653) read it as warm. The app keeps cool, the modern reading of what the herb does in the body; the old readings are shown here but do not change it.
Avoid. There is insufficient reliable safety data to consider butcher's broom safe in pregnancy, and as an alpha-adrenergic vasoconstrictor it is theoretically capable of affecting vascular tone, so authoritative consumer references advise avoidance to be safe. A specific European standardized combination product (Ruscus with hesperidin methyl chalcone and ascorbic acid) has been used under medical supervision for pregnancy-related varicose veins in some countries, but general safety in pregnancy is not established, so the default verdict is avoid. (Natural Medicines / WebMD monograph: not enough reliable information, avoid; AHPA Botanical Safety Handbook precautionary approach; ESCOP monograph, Ruscus rhizome.)
Insufficient data; caution. Formal lactation-safety studies are lacking. The e-lactancia database rates Ruscus aculeatus low risk and judges moderate use of the well-tolerated root probably compatible with breastfeeding, but because controlled data are absent and the herb is a vasoconstrictor, the prudent course is to avoid or use only briefly under professional guidance. (e-lactancia.org, Ruscus aculeatus, low-risk rating; Natural Medicines / WebMD: not enough reliable information, avoid to be safe.)
Not recommended for internal use in infants and children. There is no established pediatric dosing or safety data, and the herb has measurable adrenergic vascular activity, so it should not be given internally to children. Topical hemorrhoidal or venous preparations in children should be used only on professional advice. (Natural Medicines / WebMD monograph; general AHPA precautionary stance for vasoactive botanicals.)
Butcher's broom is a genuine vasoconstrictor: its steroidal saponins (ruscogenin, neoruscogenin) act as agonists at alpha-1 and alpha-2 adrenergic receptors on venous smooth muscle, so it narrows vessels and can raise blood pressure. Use caution in hypertension. Because it stimulates alpha-adrenergic tone, it can blunt alpha-blocking drugs (for example the terazosin and doxazosin used in benign prostatic hyperplasia and hypertension) and can add to sympathomimetic stimulants and, in theory, provoke a hypertensive response with monoamine oxidase inhibitors. Occasional mild gastrointestinal upset (nausea) is reported. Rectal bleeding or a suddenly painful, swollen leg must be investigated (hemorrhoidal bleeding can mask other pathology, and a hot, swollen, painful calf may be a deep-vein thrombosis) rather than self-treated as simple varicosity.
Pregnancy and lactation (insufficient safety data). Uncontrolled or poorly controlled hypertension (vasoconstrictor). Concurrent alpha-blocker therapy (antagonism), sympathomimetic stimulants, or monoamine oxidase inhibitors (additive vasopressor risk). Dry, cold, deficient constitutions, and Yin-deficient dryness (drying astringent). Investigate rectal bleeding and unexplained painful leg swelling before use.
Ruscus aculeatus is assessed as Least Concern globally by the IUCN and is common in parts of its Mediterranean range, but it is protected under Annex V of the EU Habitats Directive, which regulates wild harvest, and it is pressured by cutting for florist and Christmas 'false holly' greenery. The medicinal roots are still obtained almost entirely by wild collection, and unsustainable over-digging is a concern in several countries. Prefer cultivated or certified responsibly wild-harvested rhizome; the plant can be cultivated. Not listed by United Plant Savers, whose registry covers North American natives, whereas butcher's broom is an Old World species.
Not named in the canonical biblical texts. Native to the Mediterranean, North Africa, and the Middle East, it belongs to the Greco-Roman rather than the Hebrew scriptural tradition. Dioscorides (De Materia Medica) described it, probably as myrsine agria / oxymyrsine (wild myrtle, knee-holly), as a diuretic and laxative for dropsy, urinary obstruction, nephritic complaints, and stones, and Pliny (Naturalis Historia) noted its use for varicose veins and kidney disorders.
