A case of occupational asthma was reported in a pharmacist who had worked in an herb shop processing herbal materials. The patient had a positive response to dong quai ("Angelica radix," species unspecified) in a skin prick test. 

Allergic sensitivity to it was first reported by Feinberg and Watrous (1945), who elicited positive reactions to scratch tests in sensitised pharmaceutical workers. Rhinitis and asthma in subjects exposed to it as a sterilising agent is reported by Bourne et al. (1979). They elicited positive type I reactions to skin prick tests with unconjugated materials. 

Formaldehyde is a strong irritant to mucous membranes. Adverse health effects that are associated with increased VOC concentrations of formaldehyde can begin with eye and respiratory irritation (including allergy and asthma), irritability, inability to concentrate and sleeplessness, and can end up with more serious health problems. The EPA tested formaldehyde levels in a newly constructed test home that contained various UF-bonded building materials and found values below that expected (0.06 ppm), and it is not clear whether adsorption of formaldehyde, most notably by painted gypsum wallboard, contributed to this unexpected result or not [63].
