Asthma is an inflammatory breathing condition which can be aggravated by particular stimuli, and some supplements are currently being investigated as to whether the reactivity of a person to these stimuli can be reduced.

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect asthma
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
Notes
grade-b Minor High See all 4 studies
There appears to be a reduction in asthmatic symptoms associated with magnesium supplementation to a low degree, with the one study using corticosteroids alongside magnesium finding no effect. There may be a role for magnesium in aiding untreated asthma, but already medicated situations are not certain
grade-c Notable - See study
Preliminary evidence, but boswellia appeared to benefit much more people than did placebo in symptoms of asthma.
grade-c Notable Very High See 2 studies
Although more evidence is required, it appears to be more effective at suppressing asthmatic symptoms than other nutraceuticals. Mechanisms may be related to beta-adrenergic compounds (due to increasing cAMP and inducing bronchiol dilation)
