Celastrus a Chinese herb can down-modulate the severity of AA and also examined the Celastrus-induced changes in immune responses to the disease-related antigen mycobacterial heat-shock protein 65 Bhsp65 .

Celastrus was fed to LEW rats by gavage daily beginning either before Mtb challenge preventive regimen or after the onset of AA therapeutic regimen . An additional group of rats was given .
