In a mixing bowl, combine the powdered ginger and powdered mustard. Stir them together until fully blended.
Next, add the powdered freeze-dried raspberries to the mixture. Continue to mix until the color is uniform.
Slowly pour in the St. John's Wort tincture while stirring the mixture. This will create a paste-like consistency.
Finally, add the sea buckthorn seed oil and mix thoroughly until all ingredients are well incorporated.
Transfer the potion into a clean, dry jar or bottle for storage. Seal tightly and label it for future use.
