I must start this page with a word of warning: the Internet is not your Doctor, asthma attacks can kill. You should talk to a health practitioner before using any of these remedies.
My girlfriend suffers from mild asthma and she tells me that, for her, prevention is better than cure. One of her main triggers for an attack is Tartrazine a food colouring chemical that can be found in orange squash. She now avoids this. There are also some alcoholic drinks that contain Tartrazine.
She also avoids going outside unnecessarily if the weather has just changed, especially if it goes from hot to cold. When she is out she makes sure that she has her inhaler on her as panicking can exacerbate her condition.
I must note that these things work for her, other people say that smoky environments can trigger it as can dust, pets and aspirin.
The wrong sort of diet can also be a contributing factor and dairy products seem to be a culprit. According to the BMJ, a baby given milk other than their mother�s in the first four months of their lives is far more likely to develop asthma than a baby fed on breast milk alone. I have also read that milk can aggravate asthma in later life for some, as can sugary and fatty foods. A good diet therefore is essential; try and eat plenty of garlic, onions, green vegetables and salads.
Swimming is also thought to beneficial to the asthma sufferer.
I mention in our book (The selfsuficientish Bible) that Coffee can be used in an emergency, the properties in caffeine are similar (in part) to that in an inhaler. 3 cups of strong coffee if you are having an asthma attack and can’t find your inhaler should help.
Most sources that I can find seem to agree that garlic should be taken regularly. Either with meals or as garlic capsules. Personally I eat a lot of garlic, and if any recipe suggests that you use onions then (generally) you can also add a clove or two of crushed garlic. I did read that you can chew two cloves of garlic a day (nice) or even make up a drink using garlic.
Simmer clovers in water for 30 mins. Then add other ingredients until it becomes syrup-like. Drink a shot glass of this a day.
Herbal infusions will also help. Here is a recipe for one.
Chop and mix the herbs well. Simmer gently for 5 mins in 500 ml (1 pint) of water. Then strain through a coffee filter or fine cloth.
Using the same method as above you might want also try variations including herbs such as echinacea, borage, elecampane, elderflower, peppermint, ginger and thyme. In fact thyme on its own is supposed to be beneficial.
In 1747 Reverend John Wesley wrote, �A pint of could water every morning and wash the head in cold water and using the cold bath once in two weeks: Or a decoration of liquorice often gives relief; Or half pint of tar water twice a day; or live a fortnight chiefly on boiled carrots. It seldom fails. Tar water it seems is an infusion of the sap from a pine tree with cold water (nice). I am not sure if being down wind of someone who only eats carrots would be particularly pleasant either!
The ironically named John Stoner (1897) recommends using the roots of the skunk cabbage. Pulverise them and give three doses per day until cured. Give at least a does what will lay on the end of a pen knife. From what I can gather this is to be rubbed on the chest.
One of the strangest and cruellest old remedies that I have found is one from Texas. I am unsure of who came up with it or the year – keep a Chihuanhua (breed of dog) nearby and your asthma will go from you to the dog. Apparently you can’t use someone else’s dog either.
