The first thing to consider is drinking and topically applying structured water. It should make anything else you do more effective and may turn out to be the only thing you need.
And consider this:
… In mild to moderate cases, you might consider the use of natural remedies. There are actually quite a few substances that have been reported to be helpful:
Ginger and Garlic Tea: Put four minced garlic cloves in some ginger tea while it’s hot. Cool it down and drink twice a day. Some have reported a beneficial effect with just the garlic.
Other herbal teas: Ephedra, Coltsfoot, Codonopsis, Butterbur, Nettle, Chamomile, and Rosemary all have the potential to improve an asthmatic attack.
Coffee: Black unsweetened coffee is a stimulant that might make your lung function better when you are having an attack. Don’t drink more than 12 ounces at a time, as coffee can dehydrate you. Interestingly, coffee is somewhat similar in chemical structure to the asthma drug Theopylline.
Eucalyptus: Essential oil of eucalyptus, used in a steam or direct inhalation, is well-known to open airways. Rub a few drops of oil between your hands and breathe in deeply. Alternatively, a few drops in some steaming water will be good respiratory therapy.
Honey: Honey was used in the 19th century to treat asthmatic attacks. Breathe deeply from a jar of honey and you should see improvement in a few minutes. To decrease the frequency of attacks, stir one teaspoon of honey in a twelve ounce glass of water and drink it three times daily.
Turmeric: Take one teaspoon of turmeric powder in 6-8 ounces of warm water three times a day.
Licorice and Ginger: Mix licorice and ginger (1/2 teaspoon of each) in a cup of water. Warning: Licorice can raise your blood pressure.
Black Pepper, Onion, and Honey: Drink ¼ cup of onion juice with a tablespoon of honey, after adding 1/8 tablespoon of black pepper.
Mustard Oil Rub: Mix mustard oil with camphor and rub it on your chest and back. There are claims that it gives instant relief in some cases.
Gingko Biloba leaf extract capsules: Thought to decrease hypersensitivity in the lungs; not for people who are taking aspirin or ibuprofen daily, or anticoagulants like Coumadin.
Vitamin D: Some asthmatics have been diagnosed with Vitamin D deficiency.
Lobelia: Native Americans smoked this herb as a treatment for asthma! instead of smoking, try mixing tincture of lobelia with tincture of cayenne in a 3:1 ratio. Put 1 milliliter (about 20 drops) of this mixture in water at the start of an attack and repeat every thirty minutes or so.
With a number of these substances, further research is necessary to corroborate the amount of effect that they have on severe asthma, so take standard medications if your peak flow reading is 60% or less than normal.
Don’t underestimate the effect of your diet on your condition. Asthmatics should:
Replace animal proteins with plant proteins.
Increase intake of Omega-3 fatty acids
Eliminate milk and other dairy products.
Eat organically whenever possible.
Eliminate trans-fats; use extra-virgin olive oil as your main cooking oil.
Always stay well-hydrated; more fluids will make your lung secretions less viscous.
Acupuncture is thought to have some promise as well in treating the condition.
