Respiratory Health & Asthma

Reviewed by the Nimbera editorial team · Last updated May 2026

Asthma is a chronic inflammatory condition of the airways that causes recurrent episodes of wheezing, chest tightness, shortness of breath, and coughing. Airway inflammation makes the passages hypersensitive to triggers such as allergens, exercise, cold air, and respiratory infections. While natural approaches can support symptom management and reduce medication burden, asthma is a medical condition requiring professional oversight.

When to see a doctor

Seek immediate care for sudden severe breathlessness, inability to speak in full sentences, or lips/fingernails turning blue. See a doctor if symptoms are worsening, waking you at night regularly, or you are using a rescue inhaler more than twice per week.

How we rate evidence▾

Strong - Multiple randomised controlled trials or systematic reviews with consistent positive outcomes.

Moderate - At least one RCT or several high-quality observational studies with plausible mechanisms.

Limited - Small trials, animal studies, or traditional use with limited human clinical evidence.

Buteyko Breathing Technique

lifestyle
Cowie et al. (2008), Respiratory Medicine, n=56 in Buteyko group: a 6-month RCT found the proportion of patients achieving asthma control rose from 40% to 79% in the Buteyko group, and participants reduced inhaled corticosteroid use significantly more than controls (p=0.02). PMID: 18249107.

Boswellia Serrata (Indian Frankincense)

ingestible
Gupta et al. (1998), European Journal of Medical Research, n=80: a 6-week double-blind placebo-controlled RCT found 70% of patients taking 300 mg Boswellia gum resin three times daily showed measurable improvement in FEV1, FVC, peak expiratory flow rate, and eosinophil count, versus only 27% in the placebo group. PMID: 9810030.

Oral Magnesium Supplementation

ingestible
Kazaks et al. (2010), Journal of Asthma, n=55 adults with mild-to-moderate asthma: a 6.5-month placebo-controlled RCT found oral magnesium supplementation improved peak expiratory flow rate by 5.8% predicted, reduced bronchial reactivity to methacholine challenge, and significantly improved asthma quality of life scores compared with placebo. PMID: 20100026.
$10-20/month

Quercetin (Flavonoid Supplement)

ingestible
Cesarone et al. (2019), Minerva Medica, pilot registry: subjects with mild-to-moderate asthma taking quercetin phytosome (QFit) alongside standard treatment showed better daytime and nighttime symptom control, reduced rescue inhaler use, higher peak expiratory flow with less variability, and lower oxidative stress markers versus standard treatment alone. PMID: 31578841. Note: this is a pilot registry, not a blinded RCT; larger trials are needed.
