Botanical Description of Roselle Calyx
The dried calyx of Roselle typically appears somewhat conical or irregularly shaped, measuring about 2.5 to 4 cm in length and approximately 2 cm in diameter. Its color ranges from purplish-red to purplish-black. It has five prominent lobes, which are lance-shaped. Below these lobes, you can often see smaller bracteoles (about 10, also lance-shaped) that are fused with the calyx. At the base, there’s usually a hollow cavity where the fruit was previously attached. The corolla (petals) are yellowish-brown, displaying linear striations on their outer surface. The inner surface is yellowish-brown at the base, sometimes with sparse, coarse hairs. The herb is light in weight and brittle in texture. It has a faint, refreshing fragrance and a distinct sour taste.
How to Use Roselle and Dosage
Internal Administration: For a decoction (boiled preparation), typically use 9 to 15 grams. Alternatively, it can be steeped in hot water as a tea.
Preparation Method (Pao Zhi): To prepare, harvest the calyces along with the fruit. Sun-dry them for one day until they slightly shrink. Then, separate the calyces from the fruit. Place the calyces on a clean straw mat or bamboo basket and sun-dry them until fully desiccated.
