Open questions — botanical-remedies (round 3)

• Does routine 1% colloidal oatmeal use in toddlers aged 1–4 with active eczema cause measurable oat sensitisation or oat food allergy over months? (Lisante 2017 lasted 3 weeks and did not test for sensitisation; Boussault 2007 was a referred, allergy-tested population.)
• Is there any paediatric RCT of topical calendula or chamomile for atopic dermatitis with sensitisation monitoring, and does a chamomile cultivar claimed to lack allergen potential (Manzana, Kamillosan) actually avoid Compositae reactions in atopic children?
• What do parents in r/eczema, Mumsnet and similar forums report about calendula and chamomile balms in toddlers? (Reddit API returned 403 in round 3; parent-experience data still missing for these two remedies.)
