Essential Oil Internal Uses

Not just any essential oils can be taken internally. If you plan to take your oils internally, it is important that you use doTERRA essential oils. If you take an oil that isn't completely pure, it can be harmful instead of beneficial. doTERRA has the highest testing standards in the world, and as such, all of their oils are of the upmost purity.

Internal Support

There are a lot of oils that are very good for supporting internal functions, so here will mention some of the super stars.

Lifelong Vitality Pack

Everyone should be taking the Lifelong Vitality Pack. The Lifelong Vitality Pack is exactly what is sounds like. A supplement to support lifelong vitality, long lasting youth, and increase the longterm quality of life. The lifelong vitality supplement is good for almost all of these sections, so I am mentioning it here instead of adding it to every section below.

Lifelong Vitality Pack benefits:

  • General wellness and vitality
  • Antioxidant and DNA protection
  • Energy metabolism
  • Bone health
  • Immune function
  • Stress management
  • Cardiovascular health

  • Eye, brain, nervous system
  • Liver function and digestive health

Immune Function Support

doTERRA has an immune support kit that has most of the oils that are great for immune system support. However, I've listed each of the products in that kit here as well. 

The Immune Support Kit comes with a little guide on how to use each product to boost your immune system. This is especially important in the winter, when people are in school, and there are winter-time bugs traveling around. 

On Guard is an important blend to talk about. On Guard in a blend developed specifically for cleansing the systems, and boosting the immune system. On Guard comes in a hand sanitizing mistsoft gels for internal use, beadlets for internal use, a roller touch for topical use, natural tooth paste, natural mouth washthroat dropslaundry soapcleaner concentrate, and hand soap. On Guard products smell really great, and they encourage a healthy immune system. The On Guard essential oil can be diffused or you can drink it in tea or water. It has a pleasant flavor as well as a pleasant aroma. All of the products are really great at protecting your body from coming down with something.

Copiaba soothes anxiety and also helps support cardio vascular health as well as a strong immune system. Copiaba also comes in soft gels.

PB Assist + is a pre-biotic as well as a probiotic, it is extremely useful for building a strong immune system.

Oregano is an antioxidant, and is a powerful cleansing agent. When taken internally, oregano supports healthy immune function, respiratory function, and is a powerful digestion aid.

Cellular Regeneration

Pink Pepper and DDR Prime

Pink Pepper is one of the Best Oils to take internally. The medical professionals recommend taking it in combination with DDR Prime, which is the cellular support complex. DDR Prime is meant to "support cellular health, function and renewal."

Pink Pepper supports:

  • Cellular Function
  • Kidney Function
  • Liver Function
  • Cardio Vascular System
  • Vascular System
  • Lymphatic System
  • Respiratory System
  • Relaxes Nervous System

Internal Cleansing

Here I'm going to just say all of the Citrus Oil. All of the citrus oil have very similar properties, with slight difference. Citruses are very cleaning for your internal systems, and they help flush out toxins. The main health property in citrus is limonene.

Limonene is used by medical professionals for:

  • Cancer treatment
  • Prevent Cancer
  • Promote Healthy Weight-loss
  • Bronchitis treatment

Citrus Oils All Containing Limonene:

Limited Time / Promotional:

  • Kumquat 
  • Red Mandarin
  • Clementine 

Others worth mentioning that are internally cleansing:

  • Zendocrine
  • Melaleuca - Incredible cleansing properties, topically, internally, and aromatically. Supports healthy cellular function
  • Oregano  - Supports healthy Immune system

Energy and Dietary Support

I chose to put Energy and Dietary Support together, because a lot of the same oils that give you energy increase your metabolic function, a decrease hunger cravings. These two frequently go hand in hand. 

Exercise is made much easier when you add essential oils to you water. You'll be surprised at how much easier it is to exercise harder. Hugh Jackman uses doTERRA essential oils in his exercise, skincare, and sleep regimen. 


Peppermint is really the super star for energy boosting. Topically, internally, and aromatically peppermint boost energetic feeling. Drinking peppermint in your water while you exercise or throughout the day, will give you more energy, and promote positive feelings throughout the day. 

Tip: Put two drops of peppermint and 2 drops of citrus oil (I recommend Wild Orange) on your palms, rub them together, cup them over your nose and breath deeply. The energetic effect is almost instantaneous. 

Mito2Max is doTERRA's energy support blend. Mito2Max supports healthy brain function, energy throughout the day, and helps your body use oxygen efficiently. 

Healthy Weight-loss:

  • Slim & Sassy Blend
  • Citrus Oils (All of them support healthy weight-loss and promote energetic feelings)

Slim and Sassy is doTERRA's weight - loss blend. Slim and Sassy contains Peppermint, Grapefruit, Lemon, Cinnamon, and Ginger. This blend works by reducing hunger cravings, while increasing your metabolic function. 

I personally lost 15lb in a month using slim and sassy. I just added a few drops to my water all day, and drank a lot of water throughout the day. I did this for a month, and I found my hunger cravings greatly reduced, and the weight seemed to fall off. Friends of mine have lost even more weight with continued use over several months. If you combine this with exercise, I'm sure it would be even more effective.

Tip: Because of these great ingredients, Slim and Sassy is actually very good for a sore throat as well. Drink a few drops in tea or water to sooth a sore throat.

Digestion Support

Digestion is a key part of weight-loss, long term health, and detoxification. The whole process of digestion is the elimination of waste. Improper digestion can prevent you from absorbing micro and macro-nutrients, as well as keep waste inside your body longer than is healthy. This can lead to bloating, gas pain, unhealthy looking skin and hair, as well as numerous other health problems. Suffice it to say, it is important to support healthy digestion. 

Digestion Blends:

Digest Zen is doTERRA's blend for digestion. This comes in a number of forms for your preference. The pure oil you can add to tea or water for drinking. This helps your body more easily process heavy foods, and rid your body toxicity build up.

Digest Zen also come in a touch (roll on bottle), so you can apply it topically directly on your stomach or an area where there is trapped gas, to relieve it quickly.

Digest Zen also comes in tablets and soft gels.

Terra Zyme is a tablet blend that contains enzymes to help promote gut health and digestion. Balancing gut health is extremely important to lasting long term health.

Additional essential oils for digestion:


There are a lot of thing throughout the day that you can do to increase the quality of your sleep. Exercise is very important for better sleep, as well as decreasing toxic intake (foods chemicals, excessive sugar, etc). However, these are some oils that can help.
