What Are Essential Oils?

Essential oils are concentrated aromatic liquids extracted from fruits, seeds, flowers, roots, leaves, and so on. Plants create essential oils naturally and store them in tiny sacks. Fruits store their essential oils inside their skin. This essence is the main source of the odor of the plant.

Essential oils are often used for aromatherapy and in various beauty products. Manufacturers get essential oils through very delicate extraction processes. There are various options for extracting essential oils, however, the most popular types are steam distillation and cold pressing.

Here’s a video of a professor at Jade Bloom University who explains the process of essential oil extraction through distillation and cold pressing.

Health benefits and contraindications

Essential oils are known to provide a wide array of health benefits. They are widely used in aromatherapy for therapeutic purposes. Essential oils are also used during massages and are absorbed directly through the skin. 

Here are some of the main benefits of essential oils:

  • They reduce stress and anxiety. 
  • Tea tree and other essential oils are beneficial for fungal infections.
  • Essential oils like Lavender, Ylang Ylang, Chamomile, and others are known to help with sleep.
  • They are beneficial for people with chronic inflammatory conditions leading to cancer and autoimmune diseases.

Despite all the benefits essential oils offer, you should be aware of their contradictions:

  • Allergies. If you are allergic to flowers, citruses, or anything else that a specific essential oil may contain, then obviously, it’s not recommended to you.
  • Skin irritation. If your skin is prone to irritation, I’d recommend doing a quick patch test before using oils.
  • Underlying medical conditions. If you have any medical conditions, you should check with your doctor to be sure that the specific essential oil is not dangerous for you.
  • Internal use. Although some companies may recommend adding essential oils to water or food, it may cause serious issues. When you ingest essential oils, they get absorbed more quickly and may cause headaches, heart racing, and in some cases, seizures.

How much essential oil do you need to add to bath bombs?

The average dosage of essential oil should take 1-4% per ½ ounce of a bath bomb. It’s somewhere between 5 to 20 drops. This amount depends on the size of the bomb, so if you’re making a small to medium-sized one,  5 drops should be enough. But if you’re going for a large bath bomb, you can add up to 20 drops or even more.

The dosage highly depends on preference and skin type as well. If you have sensitive skin, I’d recommend starting with fewer drops to see how it works on you. You can check out this article where I share a list of bath bombs for sensitive skin. Also, the more essential oils you add to the bath bomb, the slicker the water becomes and makes the bathtub slippery, so be careful with that.

3 Essential Oil Combinations for Different Purposes

You can apply essential oils separately as well as in combination with other oils. A single essential oil can have different properties, however when used in combination with other oils, they may have other effects. 

People use essential oils in bath bombs for certain purposes. Below I will talk about the best combinations of essential oils for bath bombs that tackle the three most common needs.

For after-work relaxation

I’m sure you know the feeling when you come home from a tiring day at work, and all you want is to take a relaxing bath. There are essential oil combinations that are perfect for this cause. You can try adding 10 drops of jasmine, 5 drops of rose, and 5 drops of patchouli essential oils to create a relaxing bath bomb. 

Another blend is 10 drops of lavender, 5 drops of sandalwood, 3 drops of vetiver, and 2 drops of Roman chamomile oils. This is an amazing mix to unwind after a hard work day.

For better sleep

Have trouble with sleep? I’m sure bath bombs with these oil combinations will help you sleep like a baby. There are several oils that are good for sleeping. I’d recommend combining two, since to me personally, having diverse smells is too much, especially if you’re trying to sleep. However, it’s completely optional – you can mix as many oils as you wish.

You can choose from bergamot, chamomile, lavender, jasmine, ylang-ylang,  or sandalwood essential oils and make your own blend. As for proportions, you can add up to 10 drops of essential oil into one tablespoon of carrier oil.

For immune support

Essential oils are organic remedies for keeping a healthy immune system. Use the blend of the following oils to support your immune system: 15 drops of melaleuca, 15 drops of lemon, and 10 drops of oregano essential oil.

Over to You

Let’s wrap this up.

Essential oils are natural ingredients that are often present in various medications, self-care products like bath bombs, and aromatherapy.

There is a wide selection of essential oils for bath bombs you can choose from, including lavender, camomile, sandalwood, and much more. These essential oils have many benefits, however, you should be careful, especially if you have sensitive skin. 

When choosing a bath bomb with essential oil, I’d recommend doing a patch test to see how that oil works for you.

Now you can fill up the tub, throw in your favorite bath bomb infused with one of the essential oils mentioned above and enjoy your day!
