Jwara (Fever) & Sannipataja Jwara (Infectious Fevers)

Formulation: Flower bud decoction.

Preparation & Use: In TCM and adopted in other traditions, a decoction of the dried flower buds (Jinyinhua) is a primary remedy for the early stages of fevers, flu, sore throat, and upper respiratory infections.

Reasoning: The herb is classified as cold in nature and is believed to "disperse Wind-Heat." Pharmacologically, its antiviral and antibacterial compounds help fight the infection causing the fever.

Kasa (Cough) & Kantharoga (Throat Infections)

Formulation: Gargle with flower infusion or decoction.

Preparation & Use: A strong infusion or decoction of the flowers is used as a gargle for sore throats, tonsillitis, and mouth ulcers. It is also drunk as a tea for bronchial cough.

Reasoning: The direct antimicrobial and anti-inflammatory action soothes the inflamed mucous membranes of the throat and oral cavity.

Visha & Krimighna (Antitoxic & Anti-infective)

Formulation: Internal decoction or external wash.

Preparation & Use: Used internally for dysentery and food poisoning. Externally, a wash or poultice made from the leaves and flowers is applied to infected wounds, boils, eczema, and skin eruptions to reduce inflammation and prevent pus formation.

Reasoning: The broad-spectrum antimicrobial properties help combat both internal and external infections, while its anti-inflammatory action reduces swelling and redness.
