أنا أعرف أن أكل جوزة الطيب حرام، فماذا عن القرنفل؟

Clove is permissible to eat because it is an Indian tree-plant, and the plants of trees are permissible unless their harm to humans is proven. Imam An-Nawawi mentioned in Al-Majmoo' its permissibility for a person in a state of ihram to eat, and that it is often sought for eating and medicinal purposes.
