Pedicularis semitorta

In the high‑altitude valleys of the Qinghai–Tibetan Plateau, dried aerial parts of Pedicularis semitorta are traditionally infused in hot water to make a mild tea that eases fever and calms mild stomach upset (Liu et al., 2016). In the mountainous districts of Sichuan Province, practitioners prepare a decoction of the plant’s roots, simmering about 10 g of dried root in 300 ml of water for fifteen minutes to treat abdominal cramps and loss of appetite (Chen et al., 2019). Among Mongolian herders in the Khuvsgul region, fresh leaves are macerated into a soft pulp and applied as a poultice to minor cuts and skin irritations, the preparation being refreshed twice daily (Bazar et al., 2017).

To prepare a mild tea, place roughly two teaspoons (about 4 g) of the dried aerial parts—leaves and flowers—into a ceramic infuser, pour 250 ml of water just off the boil over them, and let the mixture steep for five to seven minutes before removing the herb. Strain the liquid and drink the warm infusion while it is still fragrant. Because the herb has a gentle diuretic effect, most traditional guides advise limiting intake to one or two cups per day and advise pregnant or nursing women to avoid it altogether.

Chemical analyses of Pedicularis semitorta have consistently shown the presence of iridoid glycosides such as aucubin and harpagoside, phenylethanoid glycosides like acteoside, and flavonoids including quercetin, all of which have demonstrated antioxidant and anti‑inflammatory activity in laboratory tests (Wu et al., 2018). These compounds provide a plausible biochemical basis for the traditional fever‑reducing and digestive‑soothing actions. Contemporary research has built on this foundation: a 2021 study in the Journal of Ethnopharmacology reported that extracts of the plant suppress pro‑inflammatory cytokines in cultured macrophages (Zhang et al., 2021). The dried herb now appears in specialty tea blends sold in Tibetan markets, and traditional healers continue to prepare decoctions for seasonal ailments, linking centuries‑old practice with current scientific interest.
