Toxicological evaluation of LivLonga^®, a polyherbal combination, in rodents

There has been keen interest on herbs and phytoconstituents with hepatoprotective property to help restore healthy liver function. Ayurveda, the ancient Indian traditional system of medicine mentions about Curcuma longa, Garcinia indica and Piper nigrum which are reported to have hepatoprotective activity. Apart from supporting metabolism, liver plays pivotal role in numerous bodily processes, immune functions to digestion, detoxification, and storage of nutrients. Factors such as sedentary lifestyle, viral infections, drugs/chemicals, high calorie diet, excess intake of alcohol etc have adverse impact on normal functioning of liver. Development of novel herbal combination with standards of safety and efficacy can help manage liver ailments and protect liver health. LivLonga^® is a polyherbal combination of scientifically validated ingredients- curcuminoids, garcinol and piperine to support healthy liver function. The present work was conducted to evaluate toxicity of LivLonga^® using in vivo models when administered orally. The acute, subacute, and subchronic toxicity studies were carried out in accordance with the test guidelines established by the Organization for Economic Cooperation and Development. A single-dose acute oral toxicity produced no toxic effects after 14 days of treatment. Four-week (subacute) and 3-months (subchronic) oral toxicity studies were conducted and observed no abnormal clinical signs, no alterations in the body weight, hematology and biochemical parameters or gross and histopathological changes. Thus, oral administration of LivLonga^® showed no signs of toxicity when dosed orally to rats, with a no observed adverse effect level (NOAEL) of 600 mg/kg/day.
