5. Traditional and Ethnobotanical uses covering the Medicinal uses.

Jwara (Fever) & Daha (Burning Sensation)

Formulation: Leaf decoction or root infusion.

Preparation & Use: In South Indian folk medicine, particularly in Kerala and Tamil Nadu, a decoction of the leaves or roots is given to reduce fever and alleviate feelings of body heat.

Reasoning: The antioxidant and anti-inflammatory properties of its flavonoids and phenolics may help modulate the body's inflammatory response during febrile illnesses.

Vrana Ropana (Wound Healing) & Twak Vikara (Skin Diseases)

Formulation: Paste of fresh leaves.

Preparation & Use: Fresh leaves are crushed into a paste and applied topically to wounds, cuts, ulcers, and skin inflammations to promote healing and reduce infection.

Reasoning: The astringent and antimicrobial properties of the leaf constituents, along with cell-proliferative effects of flavonoids, support tissue repair and protect against pathogens.

Yakrit Vikara (Liver Disorders) - Ethnobotanical Use

Formulation: Leaf juice or decoction.

Preparation & Use: In some regional traditions, the plant is used in formulations intended to support liver function and treat jaundice, though this use is less documented than for other Acanthaceae herbs like Kalmegh.

Reasoning: The antioxidant and potential anti-inflammatory effects may offer some hepatoprotective benefit, but this is an area requiring scientific validation.

Shotha (Inflammation) - General Use

Formulation: Poultice or warm leaf compress.

Preparation & Use: Leaves are warmed and applied as a compress or poultice to areas of swelling, joint pain, or inflammatory lumps.

Reasoning: The topical application leverages the plant's anti-inflammatory phytochemicals for localized relief.
