Updated: Sep 22, 2020

There are MANY natural treatments and aids for companion animals suffering from asthma and other breathing difficulties. These options can greatly aid should guardians wish to use more natural options and avoid pharmaceutical drugs that often have a list of side effects and could even cause other diseases. This article explores various medicinal herbs that have many beneficial properties that address common symptoms of asthma and other breathing issues such as airway restriction, lung remodeling, mucus build up, inflammation and more.

Please Note this article is primarily focused on the plant and its parts versus Essential Oils. I personally do not recommend them due to the cats’ very sensitive Cytochrome P450 system.



MULLEIN scientifically known as Verbascum thapsus is a wonderful herb for expelling any kind of mucus that has built up in those suffering from Asthma and other respiratory like conditions (1, 2 ). Due to compounds called polyphenols found in plants (3), Mullein is also an antioxidant, anti-inflammatory (4) (5) and anti-bacterial. Other compounds that make Mullein so extraordinary include Saponins (6), Flavonoids (7), Phenylethanoids (8) (9) and Iridoids (10) that together have further anti-inflammatory, anti-tumor and antiviral properties. Much of this herb’s parts can be used including roots, flowers and leaves all of which can be

brewed to prepare a tea. Others have boiled the leaves in water for about 5 minutes to create a steam which is then inhaled. This can aid coughing and congestion often associated with asthma. It should be noted the seeds of mullein should be avoided however (10).
