Botanical Overview
Cat Thyme (Teucrium marum) belongs to the Lamiaceae family. Limited but reliable traditional records indicate this plant has recognized medicinal applications in one or more healing traditions. The mint family (Lamiaceae) includes aromatic herbs and shrubs with square stems, opposite leaves, and two-lipped flowers. Many species produce essential oils in glandular trichomes on their leaves and stems. This family is one of the most important sources of culinary and medicinal herbs worldwide.

Traditional Uses
Cat Thyme has been traditionally used for respiratory conditions, urinary tract health, and nervous system disorders, among other applications.
Respiratory conditions.
- Expectorant
Respiratory conditions are addressed through steam inhalation of the herb’s vapors or internal use as a warm tea. The hot infusion acts as an expectorant, helping to loosen phlegm and clear congestion. Some traditions combine it with honey for coughs.
Urinary tract health.

Nervous system disorders.
- Spasm
Nervous system support involves taking the herb as a warm tea, often in the evening or before bed. The calming compounds interact with neurotransmitter systems to promote relaxation and restful sleep.
