Indian Squill

Also known as: Sea-Onion

Botanical Overview

Indian Squill (Urginea indica) is a flowering plant in the Liliaceae family. Traditional medicine systems have documented several valuable applications for this species, supported by its observed therapeutic effects. The lily family (Liliaceae) includes bulbous herbs with erect stems, alternate leaves, and showy six-parted flowers with prominent stamens. The underground bulbs serve as storage organs rich in carbohydrates. Many species contain steroidal saponins and alkaloids with medicinal properties.

Family Context

The Liliaceae family is widely distributed in temperate regions. Notable medicinal members include:

Geographic Distribution

Indian Squill has been recorded in 10 countries and territories worldwide, including Burkina Faso, Central African Republic, Ivory Coast, Cameroon, Ghana, and others.

Traditional Uses

Indian Squill has been traditionally used for respiratory conditions, urinary tract health, and pain and inflammation, among other applications.

Respiratory conditions.

  • Expectorant
  • Bronchitis
  • Cough
  • Asthma

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.

  • Diuretic

Urinary tract applications typically involve drinking the herb as a mild tea, which increases urine production and helps flush the urinary system. It may be combined with other demulcent herbs to soothe irritated tissues.

Pain and inflammation.

  • Rheumatism

For pain and inflammation, preparations are applied both topically as compresses and taken internally. A warm poultice draws blood to the area and promotes healing, while internal preparations address systemic inflammation.
