Andrographis paniculata has been used in TCM to treat fever and infections for centuries. A randomized double-blind trial found andrographis as effective as paracetamol for reducing fever in 152 pharyngotonsillitis patients. Its active constituent andrographolide demonstrates antipyretic effects comparable to acetaminophen in animal models via COX-2 inhibition.

Andrographolide, the principal diterpene lactone from Andrographis paniculata, demonstrates antipyretic effects comparable to paracetamol in animal studies. It reduces fever by inhibiting COX-2 expression and suppressing pyrogenic cytokines such as IL-1β and TNF-α. It has a long history of use in TCM for febrile illness.

Baicalin, the principal flavonoid glucoside from Baikal Skullcap (Scutellaria baicalensis), demonstrates well-documented antipyretic activity in animal studies via inhibition of pyrogenic cytokines and the NF-κB pathway.

An ethanolic leaf extract was compared against paracetamol in a brewer's yeast-induced pyrexia model in albino Wistar rats, demonstrating significant fever reduction at 50–200 mg/kg doses. Traditionally, the bark has long served as a substitute for quinine in intermittent and remittent fevers across Ayurvedic and folk medicine systems.

B. falcatum root decoctions and extracts have demonstrated antipyretic effects in multiple animal models, including fever induced by bacteria, typhoid vaccine, and fermented milk. Nasal gel and spray formulations of the essential oil also produced dose-dependent fever reduction in rats and rabbits.
