Botanical Overview
Pink Shower (Cassia grandis) belongs to the Fabaceae family. Limited but reliable traditional records indicate this plant has recognized medicinal applications in one or more healing traditions. The legume family (Fabaceae) includes trees, shrubs, and herbs that produce pods (legumes) and form nitrogen-fixing root nodules through symbiosis with bacteria. The flowers are typically pea-shaped with five petals. This large family provides food staples, timber, and numerous medicinal species.
General Description
The species is distributed from southern Mexico, to Venezuela and Ecuador. It grows in forests and open fields at lower elevations, and is known to be planted as an ornamental. In at least Costa Rica, its pods are stewed into a molasses-like syrup, taken as a sweetener and for its nutritional and medicinal effects, called Jarabe (or Miel) de Carao.

Traditional Uses
Pink Shower has been traditionally used for digestive health, respiratory conditions, and fever management.
Digestive health.
- Laxative
- Purgative
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.
- Cold
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.
Fever management.
- Fever
Febrifuge preparations are typically administered as hot teas to induce perspiration, which helps the body regulate temperature. The patient is kept warm and encouraged to rest while the herb promotes sweating.
