Capsicum is used for various problems with digestion including upset stomach, intestinal gas, stomach pain, diarrhea, and cramps. It is also used for conditions of the heart and blood vessels including poor circulation, excessive blood clotting, high cholesterol, and preventing heart disease.
Cayenne pepper has been used for a variety of ailments including heartburn, delirium, tremors, gout, paralysis, fever, dyspepsia, flatulence, sore throat, atonic dyspepsia, hemorrhoids, menorrhagia in women, nausea, tonsillitis, scarlet fever and diphtheria.
Other uses include relief of toothache, seasickness, alcoholism, malaria, and fever. It is also used to help people who have difficulty swallowing.
I personally do, and in many of my workshops and course classes, I teach students about, a "10-Day Cayenne Eyewash." It clears the sinuses, relieves allergies and asthma, strengthens the vision, brings clarity of thought and drains mucus congestion in the head. It is very strengthening and healing. Yes, it burns, but it is a healing burn, not a damaging one - do NOT do it for more than 10 days; done for too long a period, it can be damaging to the eyes. Take a small pinch of cayenne (just enough to fit on the tip of a steak knife) in about 1/4 cup of tepid water, stir well. You are going to squeeze one eye very tight and pour a bit of the cayenne water into the corner of your closed eye. I use a straw, put it in the water, close off the top with a finger - which locks a bit of water in the straw - which I then release into the corner of my eye. Then SLOWLY blink your eye allowing a tiny bit of the cayenne water to seep into the eye. Just keep blinking and allowing more water in. Hold a ball of tissue in one hand and hold to the corner of your eye to prevent the water from dripping down your face. Once the burning subsides you can stop. Do that with both eyes once a day for 10 days. You will be amazed at the relief in your head, clarity and strength.
One of my best "circulation" formulas is BLOOD WARRIOR FORMULA which has cayenne as its main ingredient:
Some people apply capsicum to the skin for pain caused by shingies, osteoarthritis, rheumatoid arthritis and fibromyalgia. It is also used topically for nerve pain (neuropathy) associated with diabetes and HIV, other types of nerve pain (neuralgia), and back pain.
Capsicum is also used on the skin to relieve muscle spasms, as a gargle for laryngitis, and to discourage thumb-sucking or nail-biting.
Some people put capsicum inside the nose to treat hay fever, migraine headache, cluster headache, and sinus infections (sinusitis).
