Blends for Internal Use: DigestZen® and Slim & Sassy®

If we know anything about essential oils, it’s that by themselves they are powerful tools, but with expert blending, their effects have a synergy that have even greater impact. The doTERRA blends DigestZen® and Slim & Sassy® are so effective for digestive and metabolic health because of the oils included in their formulation.*

DigestZen Digestive Blend (also known as the “tummy-tamer”) combines together Ginger, Fennel, Coriander, Tarragon, Anise, Caraway, and Peppermint oils. Slim & Sassy Metabolic Blend uses Grapefruit, Lemon, Peppermint, Ginger, and Cinnamon. While there is some overlap in the oils used in both, each blend brings unique benefits to the table. 

Why Internal Use?

While there are definite aromatic and topical benefits to both, the full range of benefits for both Slim & Sassy and DigestZen can be enjoyed if you use them internally. The following benefits specifically come from ingesting the oil blend itself, whether in water or in a veggie capsule:


  • Brings relief from the occasional upset stomach*
  • Helps reduce any gas or bloating*
  • Aids your digestive process, especially in cases of overeating*
  • A great supplement for general digestive health* 

Slim & Sassy

  • Like DigestZen, Slim & Sassy also calms the stomach*
  • Promotes the function of a healthy metabolism*
  • Manages any hunger cravings you may experience and prevents you from overeating*
  • Gives a revitalizing boost of energy*

To use either blend for any of the above reasons, we recommend putting them in water. For DigestZen, add one drop of DigestZen oil to four fluid ounces of liquid, and drink. For help with cravings and metabolism, add eight drops of Slim & Sassy to 16 ounces of water. Or, for those who may not like the taste, take two drops at a time in a veggie capsule. Both blends are also available as softgels (DigestZen® Softgels or Slim & Sassy® Softgels), if preferred. 

Other Blends

For the purposes of this post, we focused on digestive health, but doTERRA has created two other blends can also be used internally. These include doTERRA On Guard®, for help with the immune system, and Zendocrine® for help with cleansing and detoxification.
