Cepharanthine is an antiinflammatory and antineoplastic compound isolated from Stephania .^[1] Due to these modalities, it has been shown effective against HTLV in lab research. ^[2] Additionally, it has successfully been used to treat a diverse range of medical conditions, including radiation-induced leukopenia, idiopathic thrombocytopenic purpura, alopecia areata, alopecia pityrodes, venomous snakebites, xerostomia, sarcoidosis, refractory anemia and various cancer-related conditions. No safety issues have been observed with CEP, and side effects are very rarely reported. ^[3]
