There is little evidence to show that natural remedies for asthma are effective. So, do not replace the treatments you’ve been advised to take with natural alternatives. Taking natural treatments alongside something like Asthalin is also not recommended without first talking to your doctor as they can affect how it works.
There are some things you can do to help the condition, such as breathing techniques, which might reduce the need for preventer treatments, but you should always have your reliever medication close at hand, just in case.
