consultancy/research/educational company needs logo

This is what Quintessential was looking for in their logo design

Quintessential is a consultancy, research and educational company in the field of plant essential oils. Our clients are the pharmaceutical, cosmetic and complementary medicine industries who wish to include essential oils as active components in formulations. We also compile and host the world's only scientific database concerning essential oil bioactivity, which is available online via subscription. As well as appealing to our corporate clients, the logo must not alienate individual aromatherapists, who are major subscribers to our database.
