TheMessenger SAWsaid,"Use this 'Oud al-Hindi (Costul Hind- Indian Wood Costus) because it contains 7 types of cures, it is sniffed by the one having throat trouble, and is put inside the mouth of one suffering from pleurisy".[Saheeh al-Bukhari (5692)].
The Messenger SAWsaid," Cupping (Hijama) and Qust al-Bahri (Costul Bari - Sea Incense Costus) are the best of your remedies". He added, "You should not harm your children by treating tonsillitis by pressing their tonsils, rather use Qust al-Bahri (Sea Incense Costus)".[Saheeh al-Bukhari (5696)].
