Khalid Bin Saad states that he was travelling with Ghalib Bin Jabr, when fell ill during the journey. Ibn Abi Ateeq (nephew of Hazrat Aisha) Came to meet us. On seeing the patient, he took 5 or 7 seeds of Kalonji and ground it, mixed it in olive oil and dropped in both nostrils, Hazrat Aisha told us that Prophet Muhammad (Pbuh) stated that there was cure in black seeds for all ailments except sam. I asked him, what was sam? he told “Death”. Ghalib Bin Jabr became healthy with that treatment. Observations of the scholars of Hadith reveal that shooneez is equally effective for the diseases due to heat and cold. Zahbi states that kalonji removes the obstruction of any part of the body, expels the gases and strengthens the stomach. It is Emmenagogue, Lactogogue and Diuretic. It is an Anti-Helminthic, if taken with vinegar. It is useful in chronic cold. Inhalation of its smell is useful in common cold. The oil of Kalonji is effective in Alopecia. Half tea-spoonful, if boiled in water and taken, is helpful in Asthma and diffuses the toxic effects of Bee and Wasps. Continuous use of kalonji is effective in mad dog biting. Fumigation of kalonji is useful in respiratory diseases. It is useful in paralysis, Facial Palsy, Migraine, Amnesia and Palpitation. It is also an expectorant and antipyretic.
