Botanically called Hibiscus sabdariffa, Roselle is a tropical plant native to West Africa but cultivated across Asia and the Caribbean. In India, Roselle is locally known as ‘Gongura’ and widely used in regional cuisine. It has bright red calyces, edible leaves, and seeds. The herb is rich in vitamin C, anthocyanins, and mineral-rich fibre that support heart health, manage blood pressure and blood sugar, and promote digestion. The fruit extracts are tart and have a cranberry-like flavour, which makes them useful in teas, jams, chutneys, curries, and smoothies. Interestingly, it is a natural dye too due to its rich red pigment, which comes from calyces and is used in textiles.

Nutritional Composition Of Roselle Fruit
A nutrient-dense plant, particularly in its calyces, Roselle is a functional superfood. Here is a description of its nutritional composition:
- The calyces are low in calories and rich in antioxidants such as anthocyanins, flavonoids, and phenolic compounds
- The extracts provide a good source of vitamin C, calcium, magnesium, iron, and dietary fibre
- Per 100 grams, Roselle calyces contain about 50 calories, 1 gram of protein, and about 10 grams of carbohydrates
- The seeds are high in healthy fats, including essential fatty acids and vitamin E, supporting immune function, bone health, and cellular protection.
What Are Raw Calyces In Roselle?
Unprocessed fleshy outer parts of the roselle bloom that remain even after the flower falls off are called raw calyces. Calyces are fleshy, soft sepals that safeguard the flower bud before it blooms. Most edible and medicinal parts of the plant grow thick and juicy and thus are perfect for teas, juices, jams, sauces, and as a herbal remedial solution.
Traditional Uses And Daily Applications
Used historically in folk remedies for fever, digestive issues, hypertension, kidney and bladder stones, Roselle flower can be consumed in the following ways:
- A daily unsweetened or lightly sweetened beverage fused with other herbal teas
- Fresh young leaves in salads or curries as a tangy vegetable
- Seed powder into breakfast meals or smoothies for extra fibre and antioxidants
- Dried or frozen calyces, to be used year-round. This allows for long‑term storage in jars.
