At English Yoga Meetup we used to spoil our students with a little aroma therapy during the yoga end relaxation. Unfortunately, with the current situation we stopped this ritual because of the social distance pre-cautions.
If you still wanna experiment a little bit with aroma oils, then you can check out the following 3 places in Frankfurt to find your new favorite scent.
Hugendubel is a bookstore close to Hauptwache. They have an interesting section to everything yoga and ayurveda or health related at the ground floor. They also have a wide range of aroma oils from the German brand Primavera, which is high quality. You'll find everything here from refreshing citrus smells to calming forest-kind of scents.
Muji has a store close to Goetheplatz. They are more on the tech-savy side and sell aroma diffusor. But they also sell all kind of aroma oils. What is really nice, is that they sell small aroma oil sets, such as a travel collection or a collection of four different oils for relaxation with ylang-ylang.
Saint Charles Apothecary
This is a temporary pop-up store in Frankfurt, close to MyZeil. It's a deli that serves fresh pressed juices as well as raw vegan cakes and snacks. If you go upsatirs you'll find a wide range of skincare oils and a yoga line with oils and sprays to boost your yoga practice.
