Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Ayurvedic medicine has been practiced in for more than 2,500 years. Ashwagandha is one of the most widely utilized herbs in the system. It is thought to affect the endocrine, immune, nervous, and cardiopulmonary systems. This study is designed as a preliminary investigation of the effects of Ashwagandha on stress, inflammation, and immune modulation. Participants will take the liquid extract in cow's milk twice a day for five days. The results of initial, one-day, and final blood draws will be compared to determine participant's beginning and ending levels of cortisol, inflammatory cytokines, and immune-cell activation (CD4 T-cells, CD8 T-cells, B cells and natural killer cells). Measurements will be completed using flow cytometry and ELISA assay. The purpose of this study is to determine which effects of Ashwagandha are most suitable for further investigation.
