Teucrium kotschyanum

Teucrium kotschyanum is collected and used as a tea in Iran, especially in the Zagros, where the aerial parts are decocted as a bitter tonic for digestive complaints such as flatulence, dyspepsia, and loss of appetite; the same preparation is employed for colds and fever in folk practice (Amani and Amanlou, 2005; Ghadirian et al., 2016). Among Kurdish communities in Iraq, infusing or decocting the leaves and flowering tops in water is reported for stomach discomfort and as a diaphoretic, often taken warm (Salih et al., 2013). In Iranian and Pakistani folk medicines the aerial parts are also steeped in hot water and drunk to soothe coughs and mild bronchial irritation (Amani and Amanlou, 2005; Khan et al., 2009). These uses are consistently described as teas or decoctions and typically involve short infusions of aerial material.

A simple aqueous decoction for digestive discomfort is made by simmering 10 g of dried aerial parts (leaves, stems, and flowering tops) in 500 mL water for 15–20 minutes, straining, and drinking up to one cup 2–3 times daily after meals (Amani and Amanlou, 2005). Because the aerial parts of Teucrium species contain hepatotoxic furano neoclerodane diterpenes, use should be limited in duration; people with liver disease, pregnant or nursing women, and children should avoid self-treatment unless a qualified practitioner advises otherwise (Kavlia et al., 2012).

Well-characterized phytochemicals in Teucrium kotschyanum include diterpenes such as teucvin and 8-acetylteucvin, neoclerodane diterpenes, and flavonoids including apigenin and luteolin (Amani and Amanlou, 2005; Ghadirian et al., 2016; Hashemnejad et al., 2005). The bitter diterpenes likely contribute to the traditional stomachic actions via digestive stimulation and spasmolytic effects on smooth muscle; flavonoids and phenolics contribute to antioxidant activity relevant to cold and fever applications.

Modern studies continue to support the plant’s anti-inflammatory, spasmolytic, and hypoglycemic potential (Ghadirian et al., 2016; Hashemnejad et al., 2005), while cautionary work on Teucrium toxicity underscores the need for moderate, short-term use and qualified oversight (Kavlia et al., 2012). Dried aerial parts are available in herbal markets of Iran and some Middle Eastern diaspora communities, and decoctions remain a recognized folk remedy in those regions.

Common products:
Distilled essential oil from aerial parts is the principal commercial product, reported at yields of 0.2–0.8% (w/w) by hydrodistillation in laboratory analyses; minor yields are obtained by supercritical CO2 extraction in experimental work.

Fragrance and cosmetics:
The oil is used in perfumery as a scent component. Analyses report a sesquiterpene-rich profile dominated by caryophyllene, caryophyllene oxide, and α-humulene, with α-pinene and other monoterpenes often present as minor constituents. Properties relevant to fragrance include notable antimicrobial activity of caryophyllene oxide, which supports preservative function in fragrance compositions. Depending on national regulations, essential oils may be subject to IFRA standards on usage levels and component restrictions such as those for caryophyllene and related sesquiterpenes.

Colorants and tanning:
No documented use as natural dyes or tannins.

Wood and fiber:
No documented use for timber, fiber, or resin/gum.

Food and beverages (non-medicinal):
No documented use as a food flavoring or beverage ingredient.

Industrial and craft applications:
No documented adhesives, coatings, biofuels, pulp/paper, or fermentation feedstock applications.

Properties relevant to use:
• Rich in sesquiterpenes (β-caryophyllene, α-humulene; caryophyllene oxide commonly abundant).
• Antimicrobial activity in the oil is primarily linked to caryophyllene oxide.

Standards and regulation:
Essential oils for fragrance are generally governed by IFRA standards (e.g., fragrance compound restrictions; usage recommendations) and relevant national cosmetics regulations (e.g., EU cosmetic rules on essential oils; U.S. cosmetics guidance). Regulatory status is component-dependent.

Sustainability and sourcing:
Supplies originate from wild-harvested or cultivated shrubs in native range areas (e.g., parts of Iran) during flowering, followed by air-drying and distillation. Sustainable harvesting and cultivation help avoid overharvest of wild stands and maintain genetic diversity.
