Written or thumb printed informed consent (including audio-visual recording of consent process) obtained from the subject prior to performing any study specific procedure. 4. Subjects considered of stable health as judged by the principal investigator based on personal medical history, protocol specific laboratory parameters and clinical examination findings before entering into the study. 5. Negative urine pregnancy test for female subjects of childbearing potential at screening 6.Female participants of non-childbearing potential. 7. No clinically significant abnormal laboratory parameters at baseline as judged by the investigator. 8. Subjects willing to avoid consumption (ingestion) of chronic herbal medication during the course of the study.
