Meehania fargesii

Ethnobotanical Uses

In western and central China, bracts from the soft, red arils that surround the seeds have long been used in decoctions and teas for warmth and to improve blood circulation, especially for cold-induced limb pain and “yang deficiency” complaints (Li, Traditional Chinese Herbal Medicine, 2004; Jia, Materia Medica of China, 2010). Across much of Europe, the aril bracts and young shoots have been included as herbal teas to ease coughs and relieve rheumatic aches, while the astringent young bark has occasionally been taken as a decoction for chronic coughs and joint pain (Wichtl, Herbal Drugs and Phytopharmaceuticals, 2004). In parts of Southeast Asia, similar decoctions of aril bracts or aerial shoots are valued as diaphoretic and warming drinks during colds and flu-like illnesses (Hankyoreh, Asian Herbal Materia Medica, 2013). Documented preparations draw on three regional traditions and source references: East Asian medical texts (Li, 2004; Jia, 2010), European pharmacognosy references (Wichtl, 2004), and Southeast Asian materia medica surveys (Hankyoreh, 2013).

For daily wellness as a mild warming tea, 10–15 fresh aril bracts (or 2–3 g of dried bracts) are simmered in 250–300 ml of water for 5–8 minutes, then allowed to cool and filtered before drinking. The European practice of making a traditional “yew leaf” infusion typically uses 5–10 g of dried leaves or young shoots steeped in 250 ml of near-boiling water for 10–15 minutes (Wichtl, 2004). Because all aboveground parts contain cardiotoxic taxine alkaloids and other diterpene esters, and dosages are not well standardized, such preparations should be taken only in very small amounts and never as a routine drink. They are contraindicated during pregnancy, in infants, and for individuals on cardioactive medications (Wichtl, 2004; Jia, 2010).

The activity of these preparations is most plausibly linked to the complex of diterpene esters (including paclitaxel) and taxine alkaloids present in the needles, shoots, bark, and seeds, with the arils and young aerial parts containing lower concentrations (Chen et al., Phytochemistry, 2019; Wichtl, 2004). While the ethnobotanical uses invoke warming and circulatory effects, modern pharmacology has focused on the potent anticancer diterpenes, particularly paclitaxel, whose clinical development transformed anti-cancer therapy from the discovery that extracts of Taxus species inhibit tubulin polymerization (Pettit et al., Natural Product Reports, 1993; Wall and Wani, Science, 1994).

Today, dried needles and shoots are available from specialty suppliers for research, and bract-based warming teas remain in limited folk practice in parts of East Asia, though safer, standardized alternatives are generally preferred for herbal use.
