White Hibiscus

White hibiscus (Hibiscus sabdariffa) is a variety of hibiscus known for its pale, creamy-white flowers. It is a tropical plant, and its dried calyces (the part of the flower that encloses the petals) are used to make infusions. These calyces are typically dried after harvesting.

White hibiscus is primarily used to create herbal teas and infusions, often valued for its mild, slightly tart flavor profile that is less intense than red hibiscus. It is also used as a base for flavored beverages and sometimes as a natural coloring agent, though less vibrant than red varieties. It can be found in tea bags and powdered drink mixes.

White hibiscus is generally recognized as safe (GRAS) by the FDA for use in food. JECFA has evaluated hibiscus species and found them to be safe for consumption. Research on hibiscus, including white varieties, suggests potential benefits related to blood pressure and antioxidant activity, though more human studies are needed. Evidence is mixed on the extent of these benefits, and it is not a substitute for medical treatment.
