The warning, reported by the Nigerian outlet, highlights a potential risk associated with the popular spice, which is widely used in cooking and traditional medicine.

Turmeric contains curcumin, a compound known for its anti-inflammatory properties, and is often consumed as a supplement or in food. However, the nephrologists cited in the report suggest that overuse may pose a danger to kidney function, particularly in individuals with pre-existing conditions. The report did not specify whether the warning applies to dietary turmeric or concentrated supplements.
Punch Newspapers did not name the nephrologists or the institution behind the statement in the available summary. The outlet’s report serves as a reminder that even natural substances can carry risks when consumed in large amounts.
Further details from the nephrologists are expected to clarify safe consumption levels and identify vulnerable populations.
