Punica granatum
Pronounced Pomegranate (POM-ih-gran-it); Punica granatum (PEW-nih-kuh gruh-NAY-tum); rimmon (ree-MOHN).
Cool and dry, binding and drawing: the archetypal astringent that tightens lax, leaky, weeping tissue, stems flux and bleeding, and clears worms.
Fruit and juice: no known risk in normal dietary amounts. Root and stem bark and concentrated alkaloid or high-dose rind extracts: avoid in pregnancy. The bark carries toxic pelletierine-group alkaloids and is an emetic, motor-nerve-active taenifuge traditionally contraindicated in pregnancy; concentrated rind extracts are not established as safe. Basis: NCCIH notes fruit and juice are possibly safe in food amounts while other forms and plant parts lack pregnancy safety data; the AHPA Botanical Safety Handbook and toxicology reviews treat the alkaloid-bearing bark as a caution-class botanical. Precautionary standard: dietary fruit acceptable, avoid medicinal bark and high-dose extracts in pregnancy.
Fruit and juice: considered acceptable in dietary amounts (NCCIH: possibly safe as food; limited data on concentrated forms). Root and stem bark and alkaloid preparations: avoid while nursing, as the pelletierine-group alkaloids are toxic and have not been studied in lactation. Precautionary standard: culinary fruit acceptable, avoid medicinal bark and concentrated extracts without professional guidance.
Fruit and juice: generally well tolerated as food. Root and stem bark and isolated alkaloids: contraindicated in young children (traditionally under 5) because of the narrow toxic margin and risk of paralysis and collapse. Rind decoction has been used traditionally in small, supervised doses for childhood diarrhea, but concentrated tannin and any bark preparation should be avoided in children without professional supervision.
Two very different medicines come from one plant. The fruit, juice and modest rind preparations are gentle and food-like; the root and stem bark is a potent, narrow-margin taenifuge. Bark and its isolated alkaloids (pelletierine group) in more than small doses cause nausea, vomiting, cramping, tremor, muscular weakness, giddiness, mental confusion, double vision and mydriasis (dilated pupils), and can paralyze motor nerves. Bark preparations are practitioner-administered only, given after fasting and followed by a purgative, with no casual self-dosing. Tannin-dense rind and bark can nauseate on an empty stomach and, taken with meals, can bind iron, minerals and alkaloidal drugs, reducing their absorption. Prolonged high-tannin use is astringing and can worsen constipation.
Root and stem bark: avoid in pregnancy, lactation and in young children, and in frail, depleted or very nervous constitutions, because of alkaloid toxicity. Do not exceed practitioner-directed bark dosing. Avoid astringent bark and high-dose rind in dry, atrophic, constipated states. Culinary fruit and juice are well tolerated by most people. Those on medicines metabolized by CYP3A4 or CYP2C9 (see drug interactions) should be cautious with concentrated juice or extract.
Punica granatum is very widely cultivated across the Mediterranean, Middle East, Central and South Asia and the Americas and is not at risk; it is not a United Plant Savers listing. The sustainability concern is part-specific: stripping root and stem bark for the taenifuge use is destructive and can kill the tree, and it is now largely obsolete given safer modern anthelmintics. Favor cultivated fruit and rind (an abundant agro-industrial by-product) and avoid destructive bark harvest.
A prominent biblical fruit, Hebrew rimmon. Named among the seven species of the good land (Deuteronomy 8:8); the spies bring pomegranates from Eshcol (Numbers 13:23); worked pomegranates in blue, purple and scarlet alternate with golden bells on the hem of the high priest's robe (Exodus 28:33-34, 39:24-26); hundreds of carved pomegranates crown the pillars Jachin and Boaz in Solomon's Temple (1 Kings 7:18-20; 2 Chronicles 3:16; Jeremiah 52:22-23); and the fruit recurs throughout the Song of Solomon as an emblem of beauty and fruitfulness (Song of Solomon 4:3, 4:13, 6:11, 7:12, 8:2). Also recorded by Dioscorides (De Materia Medica) as an astringent and taenifuge.
