Qust al-Bahri (قسط البحري

Qust al-Bahri (قسط البحري), which is lighter in color and more mild.

The Prophet Mohammad صلى الله عليه وسلم taught us (see hadeeth text below) that Qust al-Bahri is a cure for:

• Sore throat and tonsillitis
• Headache
• Pleurisy (inflammation of the membrane that wraps around the lungs)
• Decreases blood sugar
• Fights cancer
• Fights bacterial and fungal infections
• Lowers inflammation
• Has antioxidant activity
• Protects the liver
• Contains apoptogenic activity (helps the body deal with stress)
• Reduces pain and fever and has anti-inflammatory effects. (source)
• Improves symptoms of ulcerative colitis (source) 

Also has activity against worm (nematode) infections. Some research shows (see here and here) that Qust al-Bahri reduces the number of worm eggs in the feces about as effectively as treatment with a standard medication called pyrantel pamoate.

This study showed that patients with throat infections who took Qust al-Bahri had remission rates similar to that associated with the use of antibiotics.

Qust al-Bahri has also been used for asthma and cough.

Qust Ul Bahri Uses:

Painful joints: Make into a paste by mixing Qust al-Bahri with olive oil until smooth. Then this paste can be massaged into areas of pain in the evening before bed. 

For unwanted skin spots, skin discoloration, scars, and burns: Mix Qust al-Bahri in equal parts with raw honey and add a very small amount of clean water to make a paste. Apply to the area once per day, for 20-30 minutes, and then wash off.

For tonsillitis, runny nose, colds and flu: Qust al-Bahri should be ground to a powder and gently snuffed in the nose. You should be lying down with your head and shoulders slightly raised and your head tilted back. You can also inhale it by mixing with olive oil and putting droplets of it in the nostrils.

For chest infections, asthma, and pleurisy: Mix a teaspoon of Qust al-Bahri with raw honey and smear on the inside of the right cheek, three times a day.

For digestive problems, IBS, Crohn’s or intestinal parasites: Crush it into a powder (I use a cheap coffee grinder) and mix a teaspoon of Qust al-Bahri with raw honey, water or other liquids. Drink this twice a day.

NOTE: There are cases of tonsillitis and chest infection, especially in children, which need to be treated with antibiotics. Natural remedies may not be enough in these cases.
