ABSTRACT
Background:
Camphora officinarum (CO) is a commonly used homeopathic remedy for treating colds, collapse, and recurrent eruptive illnesses.Objective:
Due to the non-availability of safety data on CO, the current study intended to determine the oral toxicity of CO in its ethanol-potentized dilutions 6C, 30C, and 200C in Wistar albino rats as per OECD guidelines. Materials andmethods:
A single oral dose of CO-6C, 30C, and 200C (2000 µl/kg) was administered, and the animals were monitored for behavior and mortality for up to 14 days in an acute toxicity study. In the subacute study, the effects of daily oral administration of CO-6C, 30C, and 200C (200 µl/kg) for 28 days were observed for clinical signs, change in body weight, and mortality. Hematological, biochemical, and histopathological analyses were assessed and organ weights were determined.Results:
Results indicate no mortality of CO in its potencies in the acute toxicity study and was found to be safe at 2000 µl/kg dosage in the subacute toxicity study. CO (200 µl/kg/day) did not show any signs of toxicity in the hematological, biochemical, and histopathological analyses, along with organ weights.Conclusion:
In conclusion, the findings suggest that CO in potencies of 6C, 30C, and 200C is safe up to a single oral dose of 2000 µl/kg body weight, and the No Observed Adverse Effect Level (NOAEL) was determined to be greater than 200 µl/kg/day.
