I'm torn about essential oils being on topic here or on Health.SE.
Maybe some vegans/vegetarians use essential oils in their everyday life, but it could also be related to health matters. But maybe I'm wrong, this community could be more specialized than the Health one and could share their experience on the subject.
Example questions:
- Does any essential oil can help in curing something?
- Which essential oils can be used to purify my indoor air (in addition of opening windows)?
- Can essential oils be safely ingested?
- Can essential oil alleviate the lack of something for a vegan?
These questions are just examples and more could be asked in the future. However, they are not directly related to vegan/vegetarianism. The only connection I see is the usage of a product type issued from plants (not animal).
Is this link too weak to be on topic?
What are your thoughts?
