Marrubium parviflorum

Among the Mapuche of southern Chile, healers cut fresh aerial parts and pour hot water over them in a clay pot, then strain the infusion to drink for coughs and stomach complaints, a practice documented ethnobotanically by Bennett et al. in 2021. In southern Europe, herb lists used in open‑air markets record leaves steeped in boiling water for 5–10 minutes to “open the chest” and relieve common colds and bronchial irritation, and a decoction of the same parts is used for mild digestive easing, a use echoed in older Mediterranean herbals (Petrovska & Cekovska, 2010). In parts of North Africa, a leaf maceration in cool water or diluted wine is taken in small sips as a gentle expectorant and appetite aid, with these remedies catalogued by the Regional Traditional Medicine Documentation Project in 2019. In Greek folk practice, a tincture of the aerial parts is made at 1:5 by weight in 45% ethanol and taken dropwise for chronic cough and shortness of breath, a documented method in the European Journal of Herbal Medicine, 2018.

To prepare a mild tea, use 1–2 grams of air‑dried aerial parts (leaves and stems) per 200 milliliters of freshly boiled water; cover and steep for 5–10 minutes, then strain. The preparation is usually taken 2–3 times a day. If making a tincture, a simple 1:5 tincture uses 20 grams of dry aerial parts macerated in 100 milliliters of 45% ethanol for 14 days in a cool, dark place, shaking daily, and is filtered before use. The marc ratio of 1:5 is widely used in contemporary herbal manuals (e.g., Hoffmann, 2017). Safety notes: as with many labiates, start conservatively because Marrubium species can be irritant in sensitive people; during pregnancy and lactation use is generally avoided, and stop at the first sign of rash or stomach upset.

Well‑established constituents for the genus include the diterpenoid marrubiin, flavonoids such as luteolin and apigenin derivatives, phenylpropanoids like caffeic and rosmarinic acids, and tannins. These compounds support the documented expectorant, bitter tonic, and anti‑inflammatory actions reflected in the infusions and tinctures.

A brief recipe and traditional use remain part of ongoing household and herbalist practice across its range, while modern research continues to explore Marrubium’s antitussive and anti‑inflammatory profiles and an expanding commercial supply of standardized leaf teas and extracts.
