ESSENTIAL OIL BLEND Proprietary Blend

Also known as: Essential oil blend, EOB, Proprietary essential oil blend, Essential Oil Blend

Overview

Essential oil blends are mixtures of volatile oils extracted from various plants, including herbs, spices, and medicinal plants. These blends are utilized for their aromatic and bioactive properties. In animal nutrition, they are used to support growth performance and feed efficiency in livestock. In human applications, they are used for stress reduction, sleep quality improvement, and mood enhancement. The composition of these blends can vary significantly depending on the plant sources and extraction methods used, and they are often standardized for specific bioactive compounds. Research maturity is moderate in animal nutrition, with several systematic reviews and meta-analyses available. However, in human health, the evidence is still emerging, with more robust data available for specific oils like lavender and peppermint than for proprietary blends.

Benefits

Essential oil blends have demonstrated several benefits in both animal and human studies. In animal nutrition, meta-analyses indicate improved growth performance in broilers, including increased weight gain and improved feed conversion ratios, along with enhanced gut health, as evidenced by increased villus height and crypt depth. In human health, inhaled essential oil blends, such as those containing lemon, eucalyptus, tea tree, and peppermint, have been associated with lower perceived stress and depression, as well as improved sleep quality. Some studies also suggest a trend toward improved quality of life in certain populations, although these results are mixed and not always statistically significant. The effects in animals are generally observed within weeks of supplementation, while in humans, acute effects on mood and sleep can be seen within hours to days.

How it works

Essential oil blends exert their effects through various biological pathways. In animals, they modulate the gut microbiota, reduce pathogenic bacteria, enhance nutrient absorption, and exert anti-inflammatory effects. These actions primarily impact the gastrointestinal and immune systems. In humans, the mechanism involves olfactory stimulation of the limbic system, which can modulate neurotransmitter activity, such as serotonin and GABA, and potentially exert anti-inflammatory effects. The inhaled oils act via olfactory pathways, while orally administered oils in animals are absorbed in the gut, with variable bioavailability depending on the composition. Molecular targets in animals include gut epithelial cells, immune cells, and microbial enzymes, while in humans, they include olfactory receptors, neurotransmitter receptors, and inflammatory mediators.

Side effects

Essential oil blends are generally recognized as safe (GRAS) at recommended doses, but toxicity risk increases with higher doses or prolonged use. Common side effects include mild gastrointestinal upset with oral use, skin irritation with topical use, and headache with inhalation. Uncommon side effects include allergic reactions and respiratory irritation. Rare side effects include severe allergic reactions and hepatotoxicity with certain oils. Potential drug interactions exist with sedatives, anticoagulants, and drugs metabolized by CYP450 enzymes. Contraindications include pregnancy, lactation, young children, and individuals with asthma or allergies to specific oils. Caution is advised in the elderly, immunocompromised individuals, and those with chronic respiratory conditions.

Dosage

The minimum effective dose is not well established for proprietary blends. Animal studies typically use 50–200 mg/kg of feed, with optimal dosage ranges being 100–200 mg/kg of feed. For human use, dosages are not standardized; typical aromatherapy uses 1–5 drops in a diffuser or 1–2 drops topically (diluted). The maximum safe dose varies by oil, and it is generally recommended not to exceed manufacturer recommendations. In animals, continuous dietary supplementation is common, while in humans, acute use for mood and sleep is more typical, as chronic use is not well-studied. Oral administration in humans should be approached with caution and professional guidance, while inhalation provides rapid CNS effects, although oral absorption is low and variable.

FAQs

How should essential oil blends be used safely?

Use only as directed, avoiding undiluted topical application and oral ingestion without professional guidance. For stress/sleep, use at bedtime or during periods of stress. For animal nutrition, mix with feed.

What results can I expect from using essential oil blends?

Expect moderate improvements in growth in animals, and mild to moderate improvements in mood and sleep in humans. Understand that benefits are modest and variable, and it's not a substitute for medical treatment.

Are there any misconceptions about essential oil blends?

Yes, it's important to know that they are not a substitute for medical treatment. The benefits are modest and variable, and individual results may vary.

What are the key considerations for timing and administration?

For stress and sleep, use at bedtime or during periods of stress. For animal nutrition, mix with feed. Inhalation provides rapid CNS effects, while oral absorption is low and variable.
