Uji Rendaman Daun Tanaman Jarak Pagar Terhadap Penurunan Demam

“…Jika air yang digunakan dalam proses perendaman daun adalah air panas atau mendidih, di khawatirkan akan dapat merusak senyawa atau bahkan kehilangan senyawa aktif di dalammnya [107][108][109][110][111][112][113][114] , dan senyawa tersebut yang di butuhkan dari daun jarak pagar. Senyawa yang terkandung dalam tanaman daun jarak tersebut adalah tannin [115][116][117][118][119] ,saponin dan flavonoid yang memiliki daya anti bakteri [120] ,menguatkan kekebalan tubuh [121][122][123][124][125][126][127] , anti-kanker, dan anti jamur [128] .…”
