Context - This is a proposal from Google based on our experience consuming schema.org HealthAspectEnumeration markup and working with health-related content. If it were accepted, it could (this is a tricky area...) make it easier for us and others to understand the different kinds of health aspects addressed by a piece of Web content.

https://schema.org/HealthAspectEnumeration

1. Clarify that https://schema.org/HowOrWhereHealthAspect in the context of treatments could include locations for care, drug distribution etc.

2. Add aspects for SafetyHealthAspect; EffectivenessHealthAspect; PregnancyHealthAspect; AllergiesHealthAspect; IngredientsHealthAspect; HowItWorksHealthAspect
