To make an Epsom salt bath, you can: 1 Use 2 cups of Epsom salt for a standard-size bathtub with warm water (never more than 101.5 to 102°F (38.6 to 38.8°C). 2 Pour the salt under the water spout. This allows for the salt to dissolve faster and mix fully into the bath. ... 3 Soak in the tub for at least 12 minutes (or 20, for constipation).
Find a container large enough to fully immerse your finger comfortably. Prepare the solution by dissolving ½ cup Epsom salt in a quart of hot (not boiling) water. Stir the mixture until the Epsom salt is fully dissolved. Soak your finger for 6-10 minutes, and repeat multiple times daily. Frequency is more important than duration here.
Also, people with diabetes should not use hot or warm soaks unless instructed by a physician. The benefits of Epsom salt are not limited to just your fingers, you can also use it in the bath for total body relief of sore, achy muscles. To use it in the bath, simply stir 2 cups of Epsom salt into a filled tub and soak away.
Note: Epsom salt is carried in a variety of sizes, in virtually all grocery stores and pharmacies. Find a container large enough to fully immerse your finger comfortably. Prepare the solution by dissolving ½ cup Epsom salt in a quart of hot (not boiling) water. Stir the mixture until the Epsom salt is fully dissolved.
