Identity and form
Calendula is Calendula officinalis flower material; it should not be confused with Tagetes marigold sources used for lutein.
The label should identify the source, form, preparation, and active or marker amount when those details determine comparability.
What the evidence can answer
Human research has examined Calendula in relation to skin, hair, and nail structure, connective-tissue structure. The amount, source, preparation, population, comparator, and measured outcome determine whether a result applies to a finished product.
Current WQ evidence label: Limited human evidence. This label describes the present evidence context, not a promise of benefit.
Safety and decision context
Use-context caution. Source-specific allergy and cross-contact need label review. Pregnancy and breastfeeding safety is uncertain or specifically cautioned.
Review medicines, pregnancy or breastfeeding, allergies, medical history, and the complete finished label with a qualified professional when relevant.
