Here is what I got in my document about asthma (I always type up things as I find them, and one sentence in them I just added from this
thread 
):
"Vit c (sodium ascorbate powder form) helped heal my son's asthma after using it for only a few days." from the sodium ascorbate amazon review. This mom didn't mention amount, but usually people take 2-3 grams several times a day for problem prevention. Ideally one would like to take up to bowel tolerance for healing. To test bowel tolerance to a test on the day you are home a lot, especially towards the ned of the day. Basically you start taking 2 grams of vit c every hour. Once you get loose bowels, you reached the point. Then reduce a bit and that is your dose. If you do not reach it, try larger doses each hour next day. Some people with acute infections orhuge toxin load might need 200-300 grams daily for a while. Ascorbic acid and sodium ascorbate are most ften available forms, and second one is gentler on the stomach, when one takes it in larger amounts. Always dilute it in water right before taking,
One quick remedy to keep on hand, if you find it works for you, is fennel essential oil. It is a bronchiodilator. A person can just smell it and open up their tubes, usually.
Nigella sativa ( black cumin, or black
seed), seed or seed oil. Take 1 teaspoon of oil or 1 teaspoon to 1 tablspoon of grind seed 3 times a day.
Bromelain in pineapple stem or as a supplement. 500 milligrams taken 3 times daily, taken on empty stomach.
Apply cloth soaked with ginger tea to the chest area, and also drink it.
Fenugreek seed tea
"In my use with clients, I have found Silk Tassel to be one of the FINEST of antispasmodics for menstrual cramps, dysentery (especially from
Protozoa infections), and for severe lung spasms, like the kind associated with asthma attacks. There are only a few herbs that I have witnessed, that have the potential to stop a full blown asthma attack. An extract of Silk Tassel is one such herb.
The part of the plant used as a medicine is the leaf and twigs, preferably dried, and extracted as a 1:5 plant extract, using about 50 to 60% alcohol. Dosage range can vary depending on use, but 10 to 20 drops, up to 5 times a day. I also, sometimes make a fresh plant extract with the leaves, a 1:2 ratio, 50% alcohol."

Terri Gerard from
facebook herbal group drinks plantain leaf tea during an attack.
Carmen Call from facebook herbal group says: "If allergens are causing it, Quercetin is the cure! I needed a dehumidifier and air purifier to breathe for 3 years. I took quercetin for 2 days and my asthma VANISHED. That was 2 months ago. My life has completely changed." She took Oregon's Wild Harvest, Aller-Aid with Quercetin. In each 2 capsules there are 275 mg. of quercetin and 150 mg. of nettle. There are also 250 mg. of vitamin C and 300 mg. of N-Acetyl Cysteine. It takes 1-2 weeks for most people until full results are seen, though gradual improvement will be noticed earlier. Carmen takes only one of them a day.
Raw pastured

Loquat leaves (Eriobotrya japonica) make sure to brush off fuzzy part under the leaf before tincturing or using for tea as they can irritate mucous membranes.
Take a teaspoon of mustard seed powder twice a day, can be mixed with molasses. Some people claim it cured their asthma. Mustard leaves can be be used in similar way or mixed with raw honey.

Herbalists in Ghana have long used amor seco (Desmodium adscendens) leaves to treat bronchial asthma. The treatment was so successful that it attracted attention from the scientific community. In 1977, a clinical observational study on humans showed that 1 to 2 teaspoons of dried amor seco leaf powder daily (in three dosages) produced improvement and remission in most asthma patients treated. In a study published in 2011, researchers once again validated amor seco's traditional uses as a natural remedy for asthma. They reported that the methanol extract of amor seco was the strongest in relaxing the tracheas of
mice and ethanol extracts and water extracts had the same activity but to a lesser degree. Generally, 1-3 cups of amor seco leaf tea (standard infusion) daily, 4-6 ml of a standard tincture, or 4-5 g of powdered leaves in capsules daily are used.
Other herbs which have been used to treat asthma are comfrey, cramp bark, marshmallow, wild cherry, coltsfoot, yellow dock, elecampane, garlic, ginseng, horehound, lemon and honey, licorice root, mullein, mustard, pine gum, peppermint, slippery elm, and wintergreen.
"Between the girl's gasps, Dr. Christopher gave her sips of peppermint tea until she had taken a full cup. When she finished that, in about ten minutes, he gave her a teaspoonful of tincture of lobelia. In another ten minutes, he gave her another teaspoonful, and then a few minutes later, a third teaspoonful. He had never used more than three teaspoonfuls of the tincture of lobelia, because he was always called during asthma attacks at crisis. That is the best time to clear the ailment. They sat and talked after the girl had swallowed the third teaspoonful, and then she started to throw up. She vomited continually for an hour or so until she had nothing left in her; it brought up pus and phlegm from yellows to greens to blacks. She rolled over and fell asleep, so the Christophers left. She never had another asthma attack after that, as long as she stayed on the program, and grew up to have beautiful children of her own." Peppermint tea helped to relax muscles, so she wouldn't be sore from vomiting.
