GLF

GLF is a lesser-known Young Living blend that has historically been positioned within the brand’s digestive and liver-wellness product family, taking its name from its three constituent oils: Grapefruit, Lemongrass, and Fennel. It’s not part of the everyday diffuser rotation for most households the way a blend like Thieves or Citrus Fresh is, and tends to be used more specifically as part of a targeted wellness routine.

Aroma & Composition

Grapefruit gives the blend its bright, tangy top note and is the dominant aroma in the mix. Lemongrass adds a sharp, citrusy-green middle layer, while fennel contributes a sweet, licorice-like base note that rounds out the citrus-forward combination with a touch of herbal sweetness underneath.

How People Use It

Topical use: diluted well — 2–3% or less in a carrier oil — GLF is most often massaged over the abdomen as part of a broader wellness routine focused on digestion. Patch-test on a small area of skin first, as with any new topical blend, before applying it more broadly.

In the diffuser: 3–5 drops gives a warm, herbaceous background aroma with the citrus notes still coming through, suitable for a general diffusing session even outside of any specific targeted routine.

A Note on Claims

GLF’s marketing history leans on liver and digestive wellness language, but it’s worth being direct here: essential oils used this way support a general wellness routine. They are not a treatment for liver or digestive conditions, and anyone with an existing condition should consult a physician rather than substitute oils for medical care.

Sourcing Note

Because GLF is a proprietary ratio of grapefruit, lemongrass, and fennel oils, the named Young Living product is the reliable way to get the intended blend rather than guessing at the exact proportions of the three individual oils.
