Method: Six electronic databases including the Napralert database were searched. Data were compiled based on the grade and evidence found. Results: There were no scientific evidence to support the use of Hibiscus sabdariffa during pregnancy and lactation.

Animal studies have also shown that there is a delayed puberty, elevation of body weight and BMI in female rats that consumed extracts of Hibiscus sabdariffa.
