IL-12 is a important mediator between innate immunity with specific immunity adactive and making progress specific immunity that can protect human from bactery product and virus. IL-12 make stimulating production IFN -ɣ by NK shell and progress sitolitic function shell NK and CD8+. Pasak Bumi root has potential as imunomodulator agent. Researching with using etil acetec fraction Pasak Bumi Root show fagocitosis activity (Arifah and Nurkhasanah, 2014). this Imunostimulan effect and imonomodulator is needed for caring immunity system in face on Covid 19. Clinic experiment in Japan, imunomodulator effect is reported with progress T shell, Tshell CD 4+ whith giving 200 mg/day as long 4 weeks (drug.Com)
