In a pot, combine water, onion, avocado seed, and cloves. Bring to a boil and simmer for 10–15 minutes.
Turn off the heat and add turmeric while the mixture is still warm. Let steep for 5 minutes.
Strain the mixture using a fine sieve or cloth.
Stir in the optional carrier oil for extra moisture and longer shelf life.
Pour the tonic into a clean spray or applicator bottle for easy use.
