Biological and test markers
12This visual map uses existing EH database links to show biological agents and lab markers reported as increased, decreased, or associated with this condition. These are educational relationships only; test results must be interpreted by a qualified clinician because ranges vary by lab, method, age, sex and clinical context.

Introduction / full article
Occupational Asthma
Efficacy of Alternative and Other Treatments According to GRADE* Ranking:
Selenium Supplement [1, 26, 27, 28, 29, 30, 31, 32, 33, 34]:
Please note, this management does NOT treat the condition itself. It may mildly help with some of the symptoms, and even then has insufficient evidence to back up this claim at present. IMPORTANT: Selenium is toxic in high doses. Massive overdoses can cause kidney failure, breathing difficulty and death. Selenium should only be taken at healthy levels which the body is able to tolerate.
Recommendation: no recommendation (Available evidene does not support claims that selenium helps to prevent or treat asthma)
Grade of Evidence: very low quality of evidence
Pine Bark Extract [1, 23, 24, 25]:
Please note, this management does NOT treat the condition itself. It may mildly help with some of the symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: weakly in favor (Early studies indicate potential for Pine bark extract in the treatment of asthma, but more clinical studies need to be done)
Grade of Evidence: low quality of evidence
Oleander Leaf (Nerium Oleander) [1, 19, 20, 21, 22]:
WARNING: This plant is toxic! Not to be ingested. Causes nausea, appetite loss, vomiting, drowsiness, bloody diarrhoea, seizures, irregular heartbeat, heart failure, respiratory depression and death. The plant and any of its extracts should be strictly avoided, especially by children and pregnant women.
Recommendation: Strongly against (There is insufficient evidence to prove the effectiveness of Oleander in Asthma. Please note, this plant and its extracts are poisonous, even when ingested in dry form. Many people have died of heart or respiratory failure after eating parts of the plant or its extracts.)
Grade of Evidence: low quality of evidence
Mugwort (Artemisa Vulgaris) [1, 16, 17, 18]:
Please note, this management does NOT treat the condition itself. It has been proposed only as a weak supportive symptomatic support, and even then, has been discounted due life-threatening side effects
Recommendation: No recommendation (There is insufficient evidence to support claims that mugwart helps to treat symptoms of asthma. More research is needed.)
Grade of Evidence: very low quality of evidence
Kava (Piper Methysticum) [1, 12, 13, 14, 15]:
WARNING: In rare cases, kava may lead to liver failure and other life threatening problems. The FDA warns that those who have had liver problems, or are on medicacations which may affect the liver, patients should check with their doctors before taking Kava. Other side effects include headache, upset stomach, drowsiness, weight loss, bloody urine, and muscle weakness.
Recommendation: weakly in favor (There is insufficient evidence to support claims that Kava helps to treat symptoms of asthma. More research is needed)
Grade of Evidence: low quality of evidence
Gotu Kola (Centella Asiatica, Hydrocotyle Asiatica)[1, 6, 7, 8, 9, 10, 11]:
Please note, this management does NOT treat the condition itself. It may mildly help with some of the symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: no recommendation (There is insufficient evidence to support claims that Gotu Kola helps in the treatment of asthma in any way. More research is needed.)
Grade of Evidence: low quality of evidence
Evening Primrose Oil [1, 3, 4, 5]:
Please note, this management does NOT treat the condition itself. It may mildly help with some of the symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: no recommendation (There is insufficient evidence to support claims that Primrose Oil helps to treat asthma any way.)
Grade of Evidence: very low quality of evidence
Cats Claw (Uncaria Tomentosa) [1, 2]:
Please note, this management does NOT treat the condition itself. It is proposed only as a weak supportive symptomatic support, and even then, has insufficient evidence to back up this claim at present.
Recommendation: no recomendation (insufficient evidence to support claims that Cats Claw can help to treat occupational asthma)
Grade of Evidence: very low quality of evidence
Astragalus (Astragalus Membranaceus):
Please note, this management does NOT treat the condition itself. It is proposed only as a weak supportive symptomatic support, and even then, has insufficient evidence to back up this claim at present.
Recommendation: no recommendation (There is insufficient evidence to support claims that Astragalus helps to treat asthma)
Grade of Evidence: very low quality of evidence
Neural Therapy:
Please note, this management does NOT treat the condition itself. It is proposed only as supportive symptomatic support, and even then, has insufficient evidence to back up this claim at present.
Recommendation: no recommendation (Available evidence does not support claims that Moxibustion may help to treat asthma)
Grade of Evidence: very low quality of evidence
Moxibustion:
Recommendation: no recommendation (Available evidence does not support claims that Moxibustion may help to treat asthma)
Grade of Evidence: very low quality of evidence
