I want to use the activeIngredient property
http://health-lifesci.schema.org/activeIngredient to list two active ingredients. What is the proper way to mark it up?
And once it is properly marked up, should it appear in the Google Structured author tool as 2 values assigned to 1 property, as shown below:
activeIngredient ingredient 1, ingredient 2
or, does the activeIngredient property need to appear twice, as shown below:
activeIngredient ingredient 1 activeIngredient ingredient 2
The link below shows an example where the activeIngredient property is used to describe a single ingredient. It appears at the bottom third of the page.
