Put the raspberries, herbs and vinegar in a clean glass jar.
Use a plastic lid or cover the jar. If you use a metal lid, cover the jar with wax paper and put the lid on.
After a couple of days, check the jar to make sure that the herbs are still submerged in the vinegar. If necessary, top it off with more vinegar.
Let infuse in a cool dark place for 1 month and then strain out and discard the berries and herbs.
