Hibiscus calyces are the basis of bissap, a refreshing drink enjoyed across West Africa, and of karkadé, popular in Egypt and Sudan. Deep red in colour and pleasantly tart, hibiscus makes an excellent infusion both hot and cold.
Where does hibiscus come from?
The species most commonly used in bissap is Hibiscus sabdariffa, a tropical plant cultivated in Africa and elsewhere. The dried fleshy calyces, rather than the ornamental petals found in many gardens, provide the vivid colour and tangy flavour of the infusion.
Hibiscus is also used in syrups, desserts, food colouring and traditional recipes. Mint, ginger, cinnamon and citrus pair particularly well with its acidity.
Hibiscus and digestion
Traditionally, hibiscus infusions have been associated with digestion and a refreshing drink after meals. Some experimental and clinical research has investigated effects on blood pressure and other markers, but results should not be taken as proof that drinking hibiscus treats a condition. It is best regarded as an enjoyable beverage.
Hibiscus and cardiovascular research
Some small studies have explored whether hibiscus infusions affect blood pressure or blood lipids. The findings vary, and they do not justify replacing prescribed treatment. Anyone with low blood pressure, cardiovascular medication or concerns about interactions should ask a healthcare professional for advice.
Antioxidants and colour
Hibiscus contains pigments known as anthocyanins and other polyphenols. These compounds help give the infusion its ruby-red colour. Antioxidant properties observed in a laboratory do not automatically demonstrate protection against disease in everyday use.
How to make bissap at home
Cold infusion: iced bissap
- 15–30 g dried hibiscus calyces, whole or cut
- 1 litre drinking water
- Optional lime, fresh mint, ginger or cinnamon
Place the hibiscus in cold water, cover and refrigerate for several hours or overnight. Strain, add your preferred flavourings and serve chilled with ice. Sweeten to taste if desired.
Hot hibiscus infusion
- 1 cup water at approximately 95°C
- 2 teaspoons dried hibiscus
Steep for 4–10 minutes depending on the intensity you prefer, then strain. The liquor quickly turns ruby red and has a bright, pleasantly sour taste. It can also be cooled for iced tea.

Hibiscus and bissap: frequently asked questions
Are hibiscus and bissap the same thing?
Bissap is the name commonly used for a drink made from Hibiscus sabdariffa calyces, especially in West Africa.
Does hibiscus contain caffeine?
A plain hibiscus infusion is naturally caffeine-free, unless blended with tea, mate or other caffeinated ingredients.
Can I drink hibiscus every day?
Many people enjoy it as a beverage, but quantities and personal circumstances matter. Seek medical advice if you have low blood pressure, are pregnant or take medication that could interact.
Does hibiscus cure high blood pressure?
No. The research is not a substitute for medical assessment or prescribed treatment.
More about hibiscus and the tradition of bissap
The original French article centres on Hibiscus sabdariffa, the species used to make many ruby-red hibiscus drinks, rather than the many ornamental hibiscus varieties grown for their decorative flowers. Its fleshy calyces are collected and dried, giving the infusion its striking colour and sharp, fruity flavour. Bissap is particularly associated with West African food and drink traditions, including Senegal, Guinea and neighbouring countries. Local recipes vary widely, with mint, ginger, citrus or other spices added according to the occasion and the family.
Digestion, fluid balance and blood pressure: putting traditions in context
The French text describes hibiscus as a traditional after-meal drink and discusses its reputation for diuretic effects, circulation and blood-pressure support. It also mentions a preparation of three cups a day for several weeks in research settings. Some small clinical studies have indeed investigated hibiscus, but their results cannot justify a promise to treat hypertension, high cholesterol or diabetes through an ordinary infusion. Anyone taking blood-pressure medication, managing a chronic illness, or who is pregnant or breastfeeding should obtain individual advice before drinking large quantities regularly.
Why hibiscus has such an intense colour
Its red-violet pigments are anthocyanins, plant compounds widely studied for antioxidant activity. The French article refers to a 2010 comparison of drinks carried out by researchers in Oslo; such laboratory rankings describe measured antioxidant properties under particular conditions, not a ranking of proven health benefits for consumers. Hibiscus is first and foremost a delicious, naturally caffeine-free drink with a pleasantly tart character.
Two preparation methods from the original recipe
- Cold-steeped bissap: put approximately 15–30 g of dried hibiscus flowers into one litre of cold water. Refrigerate for at least two hours, or leave overnight for a more pronounced flavour. Add lime wedges, a few mint leaves or spices if you wish, and serve chilled with ice.
- Hot hibiscus infusion: steep two teaspoons of the dried flowers in one cup of water at about 95°C for four to ten minutes, according to the intensity you prefer. The liquid quickly becomes ruby red and takes on its characteristic tang.
These methods are serving suggestions, not therapeutic doses. When cold-brewing dried botanicals, use clean utensils, potable water and appropriate food-safety precautions; prepare small quantities and keep the drink refrigerated.
