Best herbs for Asthma

I have read a lot of different things about herbs and asthma I just wanted to see if there is a good perennial herb for this?

As a child i had astma. I grew over it. My book says there is nothing that is scientifically proven. Herbs excist that help against bronchitis though. Would you like me to list them?

I have used comfrey to handle asthma attacks. I tear off a small portion of leaf no bigger than my finger tip and chew it up and swallow. I had read about it in a book somewhere and we had a comfrey plant so I gave it a try one day when I didn't have an inhaler handy. It did the trick so I never hesitated to turn to it again. I've not had any asthma symptoms in years  but I still keep some comfrey growing in the garden just in case.

It may be counter intuitive but the herb/weed whose Latin name means “useful plant” but is not to be discussed on this forum has helped my asthma greatly. It has been studied and proven to work in clinical trials, particularly certain strains. I had asthma growing up to a fairly serious degree buy have had no attacks since starting regular use of the useful plant. This was tested and proven in thru hiking the Pct, doing 20+mi a day at 10k ft plus for weeks on end.

Ha re herbs. Not that there aren't a number of key ones or a partic one that may help, but asthma is about breathing itself and turns out most important and so immediately helpful is a review of breathing practices, emphasis and such. Check out vids here to get a sense of....well some of hese videos will get to the eat of the matter. Basically, breathing is counterintuitively a less is more thing. Go figure, eh: https://www.youtube.com/results?search_query=buteyko+breathing+method   I only mean to say consider this first, then herbs second, cuz breathing comes first in asthma.It just does, OgreNick

I think you are totally right about the breathing practices as well, as I saw with a girl on a trail crew I lead who had asthma and who was in no shape to be on a backcountry crew. She learned that with controlled, mindful breathing so she would be fine 90% of the time she would have otherwise have been be overusing her inhaler. In my experience I can control my breathing mentally as long as I don’t panic, and I think this really can only come from experience doing it. It’s also amazing from teaching swimming lessons how much of a difference having been taught mindful breathing makes in learning to breathe while swimming. This mindful breath control, in even young kids, seemed to correlate strongly with parents from cultures that seem to value and teach it.

In Nor Amer. the Bouteyko Method is only taught, or expressly taught as a mere asthma fix. This is so not to step on toes of allopathy (western medicine), which want only petrol based pharmaceuticals and surgery, not herbs nor practices that can keep or make you healthy, as there's no busine$$ in that. For instance, this method can help vs. constipation (lotsa drugs for that) as well as against insomnia, another cash cow. So shshshsh it from the rafters!

I found that an Osha Root Tincture was very effective to reduce my allergy caused asthma.  It worked so well that I stopped taking my 3 prescriptions and used only the Osha Root tincture.  You can buy this tincture at many places but learn to make your own.  Alcohol and then hot water extraction is what I have now.  
I used to have very tight congestion that was hard to cough up and albuterol helped some but I was using it too much.  Osha Root was even better than many shots of albuterol and made the flem very loose so a quick walk would loosen everything up andwould be good for 4 to 5 hours or more.
I have been going to immunotherapy and am almost clear of asthma now. I wish I had done this decades ago.

Mullein gives me considerable relief for asthma. I would recommend boiling for five minutes rather than just steeping, and drinking as a tea, even though I *cough* have enjoyed smoking it. I think when I smoke it the long term damage of inhaling carcinagens (I know I'm spelling that wrong but I'm TOO LAZY to look it up) outweighs the short-term benefit of loosening mucus, so I recommend the tea. You can even boil it in milk if you don't mind cleaning up the frothy mess! I kinda find the milk film on top delicious but I'm preeettty sure most people would find the slimy film gross. I get better results from stuff I pick along the roadside than what I've bought online.

I still say breathing is the best herb (medicine): https://www.youtube.com/watch?v=ADf6Ol1KmmY even tho i'm into herbology

Eucalyptus essential oil really helped my son during asthma attacks. I would fill a cup with boiling water and squirt a few drops of eucalyptus EO into it. He'd lean over the steaming cup with a towel over his head, inhaling the steam. Care must be taken because the steam is hot, but it delivers the eucalyptus wonderfully and opens up the airways.

Not a herb but a lung flutter device can help. I use it to help break up congestion and expel it.

As an asthmatic this is what I do when my chest is tight and it works great! I also make my own version of that vicks vapour rub, that's beeswax, coconut oil and a couple drops eucalyptus oil.
