Essential Oil-Based Product System for Digestive Support
Efficacy and Safety of an Essential Oil-Based Product System for Digestive Support
This study aims to evaluate the efficacy of specific essential oils. Efficacy will be evaluated through changes, if any, to hsCRP, gene expression, and standard hematologic and metabolic parameters, as well as subjective health changes as measured by Gastrointestinal Symptom Rating Scale (GSRS), PROMIS Global Health survey, PROMIS Fatigue Scale, Immune Fitness Item Scale (IFIS), and the Immune Status Questionnaire (ISQ) in healthy volunteers. The main questions it aims to answer are:
- Do specific essential oils affect gene expression and hematologic and metabolic parameters as measured in blood?
- How do essential oils affect gut microbiome?
- How does daily use of specific essential oils affect subjective quality of life and health parameters?
- Is ingesting and topically applying specific essential oils daily safe, as measured by laboratory tests and adverse events?
Two study products will be used: oil for topical use, supplement for internal use. The two products will be used together and compared to a placebo group. The topical oil contains a blend of ginger essential oil, peppermint essential oil, caraway essential oil, coriander essential oil, and anise essential oil. The supplement contains everything the oil has, plus anise essential oil.
Participants will:
- Be assigned one of the two groups.
- Use the oil topically once each day for 4 weeks.
- Take one supplement in the morning and one in the evening every day for 4 weeks.
- Attend 2 study visits in which they provide blood and urine (females only) samples.
- Complete 2 stool collection/microbiome kits
- Complete surveys and subjective health assessments

Groupe de participants / Bras |
Intervention / Traitement |
|---|---|
|
Expérimental: Dietary supplement and topical oil
Participants take two capsules of the dietary supplement (one capsule in the morning and one in the evening) every day for 4 weeks.
Participants will also place 2 mL of the oil on their forearms and stomach once daily at bedtime for 4 weeks.
|
Internal use will entail ingesting Hypromellose capsules containing 135 mg essential oil and 365 mg extra virgin oil.
The essential oils in the supplement are peppermint, coriander, ginger, caraway, cardamom, fennel, and anise.
Participants will be instructed to take one capsule in the morning with food and one capsule in the evening with food, at least 3 hours before bedtime.
Placebo will be olive oil capsules of the same size and color.
Topical use will entail applying the DigestZen oil blend diluted to 10% in fractionated coconut oil using a metered dropper.
Participants will be instructed to add 2mL to the skin of the inner forearms and belly area and massage until oil has absorbed.
The application will happen once per day at bedtime.
Placebo will contain fractionated coconut oil with a diluted single constituent for aroma and food coloring.

Comparateur placebo: Placebo
Participants assigned the placebo study products will follow the same use directions as those in the active group.
Placebo topical oil will contain fractionated coconut oil with a diluted single constituent for aroma and food coloring.
The placebo supplement group will take a supplement that contains olive oil, and will be the same size and color as the active supplement.

Placebo will be olive oil capsules of the same size and color as the active capsules.
Placebo essential oil will contain fractionated coconut oil with diluted single constituent for aroma and food coloring.

|
GSRS
Délai: 4 weeks
|
Looking for within- and between treatment changes to Gastrointestinal Symptom Rating Scale (GSRS) from baseline to completion.
The GSRS uses a 7-point Likert scale for the 15 questions regarding gastrointestinal symptoms with answers ranging from "No discomfort at all" to "Very severe discomfort."
Scores range from 15 to 105, and the total score is the sum of all item scores.
Higher scores indicate more severe GI symptoms.
