Hibiscus, scientifically known as Hibiscus sabdariffa, belongs to the Malvaceae family. It is believed to have originated in Western India and Asia, and is also known by the name Carcade. The plant is widely recognized for its medicinal properties and is a staple in various traditional healing practices.
The parts of the hibiscus plant used for medicinal purposes are primarily the flowers, specifically the calyx after fertilization. This part of the plant is processed into a drug form for use in different treatments.
Hibiscus is rich in several chemical constituents that contribute to its medicinal properties. These include tannins, flavonoids, anthocyanins, vitamin C, mucilages, and organic acids such as hibiscus, malic, and tartaric acids.
Hibiscus is revered for its various healing properties. The infusion made from hibiscus flowers, also known as carcadè, is not only a thirst-quenching drink but also a rich source of vitamin C and polyphenols, which have potent antioxidant activity.
Hibiscus is known for its laxative properties, attributed to its high content of poorly absorbable organic acids. Additionally, hibiscus extract has been found to exert a relaxing effect on uterine smooth muscles.
One of the most interesting aspects of hibiscus is its potential antihypertensive activity. Some studies have suggested that the effectiveness of hibiscus in lowering high blood pressure levels is comparable to certain conventional medications. This activity is thought to be due to the anthocyanins present in the plant.
In a similar vein, hibiscus has been compared to diuretics for its potential in combating mild to moderate hypertension. The results of such studies have been promising, with hibiscus showing not only effectiveness but also a longer duration of action without causing electrolyte imbalances.
However, while these findings are encouraging, they are preliminary. More comprehensive clinical studies are needed to confirm these therapeutic applications of hibiscus.
Beyond formal medicinal use, hibiscus also finds a place in traditional and folk medicine. It is used to make refreshing, thirst-quenching, and diuretic drinks. In folk medicine, hibiscus is used as a remedy for loss of appetite and colds.
In traditional Chinese medicine, hibiscus is used in various preparations for treating skin inflammation and swelling, burns, conjunctivitis, and even certain skin infections.
However, it's important to note that these traditional uses of hibiscus are not universally approved or supported by experimental tests. Therefore, their therapeutic efficacy may vary, and in some cases, they may even be harmful to health.
Although hibiscus has many potential benefits, it's important to be aware of possible contraindications. Those with a proven hypersensitivity to one or more components of hibiscus should avoid its use.
As for pharmacological interactions, there is currently no known interaction between hibiscus and other drugs. However, it's always advisable to consult with a healthcare provider before starting any new treatment.
