WARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
Antibacterial (melioidosis), antifungal, antioxidant, antipyretic (fever reducer), antiviral, atherosclerosis (hardening of the arteries), cancer, contraceptive, flavoring agent, hypercholesterolemia (high cholesterol), leukemia, liver diseases, liver protection, pain (antinociceptive), renal stone disease, weight loss.


Adults (18 years and older):

There is no proven effective dose for hibiscus, although an herbal infusion prepared with 10 grams of dry calyx from Hibiscus sabdariffa with 0.51 water (9.6mg anthocyanins content), daily before breakfast showed similar results as captopril 25 milligrams twice a day for four weeks.

Children (younger than 18 years):

There is no proven safe or effective dose for hibiscus in children.


DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.


Avoid in individuals with a known allergy or hypersensitivity to hibiscus, its constituents, or members of the Malvaceae family. Reported allergy symptoms include skin rash and hives.

Side Effects and Warnings

There is limited reported safety data about hibiscus, although it is popularly used as a tea.

Although not well studied in humans, excessive doses of hibiscus for relatively long periods may have antifertility effects. One study found that hibiscus tea contained polycyclic aromatic hydrocarbons (PAHs). PAHs have been associated with birth defects and cancer. The sources of PAHs in food are predominantly from environmental pollution and food processing. Use cautiously in patients with hypertension or hypotension (high or low blood pressure), as hibiscus may lower blood pressure.

Pregnancy and Breastfeeding

Hibiscus is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence. However, Hibiscus tiliaceus has been used throughout the Vanuatu archipelago to speed childbirth. In theory, excessive doses of hibiscus for relatively long periods may have antifertility activity, and caution is advised.
