This plant has earned a place in traditional medicine through its consistent therapeutic benefits, recorded across multiple cultures. 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.

General Description

It is widely cultivated throughout the Southeast Asian tropics. It is native to tropical and subtropical regions of Asia, Australia and the western Pacific. This plant has escaped from cultivation and has naturalized in many tropical regions of the Americas. It is an agricultural and environmental weed.

Digestive health.

  • Laxative
  • Ache(Stomach)

For digestive complaints, the herb is typically prepared as a tea or decoction taken before meals. The bitter compounds stimulate digestive secretions and improve nutrient absorption. Some traditions use the powdered root or leaves in small doses as a stomachic tonic.

Respiratory conditions.

  • Cough

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.

Skin and wound care.

  • Ringworm

For skin conditions, the fresh or dried plant is applied topically as a poultice, wash, or compress. A strong decoction can be used to clean wounds and sores. The antimicrobial properties help prevent infection while promoting tissue repair.
