How much of this bath salt should I use per bath, and is there anything special about how to add it?

For a standard-sized bathtub, a typical starting point is about 100-150 grams of bath salts, which is roughly equivalent to one large handful or half a cup. You can adjust this amount based on your personal preference for intensity, your tub's size, and how concentrated you want the herbal aroma to be. For a lighter, more subtle soak, you can use less. It's most effective to add the salt under the running tap while the tub is filling, as the water flow helps dissolve the salt crystals completely and distributes the sage and yarrow extracts evenly throughout the water before you get in. This method prevents undissolved granules from settling at the bottom, ensuring a consistent experience. After your bath, rinse the tub with clean water to prevent any potential residue build-up from the salt mixture.
