Very easy, and greatly appreciated by stressed-out friends and family. You can use other essential oils as well – try peppermint or a blend of citrus scents, for example.
A few words on essential oils: Be sure to use only “essential oil”, and avoid anything labeled “fragrance oil” – those tend to have synthetic ingredients, and are not for bath and body use. Aura Cacia is a very good brand, and is widely available at herb shops and health/natural food stores.
Exercise caution when using essential oils – they are very, very concentrated and some can damage surfaces or even skin in their undiluted form! Please research the properties of any given oil before working with it. If you experience any allergic symptoms while making your salts, stop immediately! (For example… I’m sensitive to Rose Geranium oil – it has made my lips swell up like a balloon in the past… this is a dangerous reaction, so I don’t use that oil at all.) For cleanup, alcohol is a good solvent. I use either (cheap) vodka, or pure-grain alcohol.
That said, Lavender tends to be one of the milder oils, and can usually be applied directly to the skin. Please test a little on the inside of your arm before using, to make sure you don’t react badly to it. If any redness, swelling, or other symptoms occur within 24 hours, this isn’t the oil for you. (If you test other oils, be sure to dilute before applying to your skin. One or two drops in a teaspoon of olive oil works well for this.)
And finally… the recipe!
- 1 cup sea salt (coarse or fine)
- 2 Tbsp. Epsom Salts
- 15 drops Lavender essential oil
It's best to have "dedicated" bowls & spoons for essential oil work, and not use them for food. (Goodwill!)
- Stainless steel, glass, or ceramic bowl (Do not use plastic or aluminum, which will react with the oil)
- Eyedropper or pipette, unless your essential oil has its own dropper top attached
- Stainless steel spoon
Drip about half of the lavender oil into the sea salt, then stir well. Repeat with the rest of the oil, stir again, then add the Epsom salts and stir once more. Keep in a clean, airtight jar, in moderate temperatures. Will keep for a long time, but the scent is best if used within a month or two. To use, pour about ½ cup of bath salts into warm bath water. Swish to dissolve, especially if using coarse sea salt. Step in and enjoy!
To make in bulk:
- 5 lbs. sea salt
- 10 Tbsp. Epsom salts
- 1 tsp lavender essential oil
