Women often feel physically and mentally unwell before their period. On the one hand, hibiscus has an antidepressant effect and, on the other hand, it interferes with the hormone balance, which can be both positive and negative. So you should drink it with caution, as hibiscus can increase estrogen levels and thus upset the hormone balance. However, a cup of hibiscus tea cannot do any harm against PMS. In Africa, hibiscus is considered an antispasmodic remedy that relaxes the uterus.
However, pregnant women should definitely not eat it, as bladder and uterine contractions have been observed. So this can lead to the loss of the unborn child.
