☯ TCM Properties
Eliminates Dampness and dispels Wind; Controls bleeding; Alleviates pain
Traditional Chinese Uses
Sweet and sour with a neutral nature, Shui Duo Nian (rose myrtle root) eliminates Dampness and dispels Wind, controls bleeding and alleviates pain. It is used mainly for Wind-Damp painful obstruction (rheumatic joint and low-back or foot pain), and as a Blood-astringing herb for uterine bleeding (metrorrhagia), haemorrhoidal bleeding and other chronic haemorrhage. It also settles epigastric and abdominal pain from disharmony of the middle burner and is applied to hepatitis, chronic dysentery and diarrhoea. Externally the root or leaf decoction is used to wash and stanch bleeding wounds, and it features in folk remedies for snakebite and corneal injury. It is a southern-Chinese folk herb, typically decocted 6–15 g; the sour-astringent action suits leakage and bleeding patterns rather than acute excess-Heat.
Botanical Description
Shui Duo Nian (水哆哟) is the root of Rhodomyrtus tomentosa (Aiton) Hassk., the rose myrtle or downy myrtle (Myrtaceae). It is an evergreen shrub 1–2(–3) m tall with young branches, undersides of leaves and buds densely covered in soft grey-white tomentum. The opposite, leathery leaves are elliptic with three prominent longitudinal veins. Showy five-petalled flowers 2–4 cm across open rose-pink to purplish, followed by fleshy, dark purple, edible berry-like fruits crowned by the persistent calyx. The medicinal part is the woody root, dug year-round, washed, sliced and sun-dried; leaves and fruit are used secondarily. It thrives on acidic hill soils and can form dense thickets.
Sunny hill slopes, open pine woodland, heathy grassland and disturbed acidic soils at low to middle elevations in the humid subtropics.
