A lot of people use black seed oil to treat inflammation, but for some, direct application can irritate skin further. Instead, dilute it in water first. This is done by adding about ten drops of oil into 8 ounces (230 g) of water. You’ll also end up using less of the oil, so one bottle can provide continual treatment for longer. For any swollen or red area, treat it with diluted oil. Once you have mixed the oil into a bowl of warm water, dip a cotton ball into it. Dab it on the irritation gently. For extra effect, you can hold the cotton ball in place or dip the irritated area in the water for five minutes. Spraying your body with the water and oil mixture may also relieve fever. Fill a pot with 2 US quarts (1,900 ml) of water and add about ten drops of black seed oil to it. Let the water boil. As you wait, you can place a clean, warm towel over your face to open up your pores. Stay near the pot for five minutes, but don’t lean over it, since the steam could burn you. For toothaches and headaches, you can rub the oil into the painful area. Get a drop or two of oil on your finger or a cotton ball. Dab the oil onto your aching tooth or massage it into your temples. With any luck, the pain will abate. Try adding a few drops of oil to a cloth. Throughout the day, smell it. If you have a vaporizer on hand, you can also add a few drops to it and breathe in the oil’s aroma. Black seed oil users claim that this aroma relaxes your muscles, preventing headaches or asthma attacks.
