Final answer:
Bab el sham is facing seasonal demand for hibiscus (karkaden) during certain times of the year, such as Ramadan, due to increased consumption after breaking the fast. Heat during mid-summer in Arab cities makes people thirstier and contributes to the higher demand for hibiscus.
Step-by-step explanation:
Bab el sham is facing seasonal demand for hibiscus (karkaden) during certain times of the year, including Ramadan. During Ramadan, the demand for hibiscus increases because faithful Muslims often consume it after breaking their fast. This is especially true when Ramadan falls in mid-summer and the heat makes people thirstier.
