efficacy and tolerability of sensoril® in improving immunity and thereby reducing incidence of upper respiratory tract infections

Conditions: Immune Health

Summary: to assess the efficacy and safety of a standardized withania somnifera extract (sensoril®) as an immunomodulator in individuals suffering from recurrent urtis. the study population will be administered with this unique blend of ws extract for 12 weeks and will be assessed as per the study designated efficacy and safety variables.

(note - a standard alcoholic drink contains approximately 14 grams of alcohol, which is equivalent to 12 ounces of beer (\~5% alcohol), 8.5 ounces of malt liquor (\~9% alcohol), 5 ounces of wine (\~12% alcohol), 3.5 ounces of fortified wine (e.g., sherry or port), or 1.5 ounces of liquor (distilled spirits; \~40% alcohol). 18. binge drinkers, defined as 4 or more sad for women, and 5 or more sad for men, in a 2-hour time frame. 19. history or presence of severe acute respiratory syndrome coronavirus 2 (sars-cov-2) infection. 20. participants who have clinically significant following severe illness (i.e., cardiovascular, endocrine system, immune system, respiratory system, hepatobiliary system, kidney and urinary system, neuropsychiatric, musculoskeletal, inflammatory, blood and tumors, gastrointestinal diseases, etc.) 21. females who are pregnant/planning to be pregnant/lactating or taking any oral contraceptives. 22. any condition that could, in the opinion of the investigator, preclude the participant's ability to successfully and safely complete the study or that may confound study outcomes.
