Aromabath, as you have probably realised, is an aromatherapy session during a bath. Which means we're going to need essential oils.

A minute of the importance of safety precautions when using essential oils in water:
Essential oils are lipophilic - hydrophobic (i.e. they literally "run" from water to wherever it goes: on you, your skin and mucous membranes!) and do not dissolve in water
To dissolve essential oil in the bath we need an emulsifier: liquid shower gel, shampoo, hydrophilic oil, polysorbate, vegetable oil (it will dissolve the essential oil, but it will not dissolve in water),
Salt (as well as sugar and honey) is not an emulsifier in this case!!! The salt will dissolve and the essential oil will remain on the surface of the water
Essential oil in its pure form can irritate the skin and mucous membranes very strongly, especially in hot water.

So how to use essential oils in the bath?
We take 5-10 drops of essential oils and in proportion of 1/4 mix them with shower gel or liquid soap with a spoon in a glass jar.
add the mixture to the filled bathtub and immerse yourself in it for 10-15 minutes.

What does it give us?

• relaxation of the whole body and mind
• muscle pain relief
• double the effect on the respiratory tract
• improved circulation
• detox
• peace and quiet in your head

⠀
Of course, depending on the purpose, we select essential oils as well.
For example,
pine, eucalyptus, tea tree are good for the respiratory tract,
lavender, geranium - relaxing, also good for infections,
orange, lemon, bergamot - lymphatic drainage and also sanitation of the upper respiratory tract. Lemon and bergamot are stimulating and invigorating (you can drip them on the tiles in the shower in the morning), and orange is better in the evening)
But in general, if you like any fragrance of essential oil, then do not worry about its properties, take a bath with it, it means that your body requires it now) but it is important not to exceed the dosage and be sure to dissolve in something!
⠀
Some essential oils are particularly irritating to the skin. Such as, bay, cumin, cinnamon, clove, lemongrass, peppermint, etc. It is best not to use them for bathing at all.
