Not so long ago traditional home remedies were used and passed down by generations for ailments because they worked and provided relief without killing the sufferer. Found this from The Old Farmer’s Almanac on Traditional Home Remedies for asthma sufferers, and what you can do at home.
Asthma Alleviator Source: Traditional Home Remedies by Martha White (pg. 27)
1 pint Irish moss jelly (Irish moss is a North Atlantic seaweed. The jelly is available at health food stores and some pharmacies.)
½ yellow onion
2 cloves garlic
½ cup honey
Combine the Irish moss jelly, onion, and garlic in a saucepan and simmer <covered> for 30 minutes. Strain through a sieve and add honey. Take one tablespoon every couple hours as needed.
Drink chamomile tea, a natural antihistamine. Or, decoct Roman chamomile flowers and inhale the steam.
If your asthma is allergy based and pollen is the source of your trouble, add honey to any tea and drink it in frequent does to build up your immunity. Or, dilute honey with an equal amount of water or lemon juice and take by the tablespoon. (“The hand that gave the wound must give the cure.”)
Suck horehound candy or make a tea of decocted horehound leaves.
