This blend encourages relaxation and delivers a refreshing cooling sensation when applied to the skin.

How It Works

How Tei Fu Oil Cools, Relaxes, and Soothes

The effectiveness of tei fu oil lies in the synergy of its six essential oil ingredients, each contributing distinct properties that work together to promote comfort and relaxation.

At the heart of the blend, menthol activates TRPM8 cold receptors in the skin, creating an immediate cooling sensation. Research suggests that menthol acts as a counterirritant — initially stimulating nerve endings and then desensitizing them, which may help reduce the perception of discomfort. Camphor works through related but distinct pathways, activating TRPV3 receptors and inhibiting TRPA1, which studies suggest contributes to its warming-then-cooling analgesic effect and its traditional use as a rubefacient that may promote local blood flow.

Wintergreen provides methyl salicylate, a natural compound structurally related to aspirin, which acts as a counterirritant and rubefacient upon topical application. Eucalyptus contributes 1,8-cineole (eucalyptol), which research has linked to anti-inflammatory and mucolytic activity. Meanwhile, Lavender brings linalool and linalyl acetate — compounds that studies suggest modulate GABAergic pathways, promoting a sense of calm. Clove rounds out the blend with eugenol, traditionally valued for its soothing and warming properties.

Together, these oils create a multi-layered sensory experience — cool and warm, calming and invigorating — making tei fu oil a truly versatile topical blend.

What's inside

Key ingredients

pure Menthol oil

Menthol is a monoterpenoid compound found naturally in mint plants such as cornmint (Mentha canadensis) and peppermint (Mentha x piperita), with a history of medicinal use dating back over 2,000 years. It works primarily by activating TRPM8 cold receptors in sensory neurons, generating the characteristic cooling sensation, and then desensitizing nerve endings, which may reduce pain perception. Research suggests menthol supports muscle recovery — studies indicate that topical menthol may reduce post-exercise muscle soreness and has been shown to outperform ice in preserving muscle function during recovery from delayed onset muscle soreness (DOMS). Clinical studies have also evaluated menthol for muscle tension and soreness, finding significant pain reduction compared to placebo and ice through TRPM8-mediated counterirritation and localized vasoactive effects. Menthol is FDA-approved as an OTC counterirritant and is among the best-documented natural topical analgesics for musculoskeletal conditions, with evidence from randomized controlled trials supporting its use for muscle strain, DOMS, joint discomfort, and general musculoskeletal comfort. Research also suggests it may support relief from backache through its counterirritant properties and sodium channel blockade.

pure Camphor oil

Camphor is a terpenoid ketone derived from the camphor tree (Cinnamomum camphora), with a rich history stretching back to sixth-century traditional Chinese medicine and ancient Ayurvedic practice, where it was used for muscle pain, inflammation, and congestion. Pharmacologically, camphor acts as a counterirritant by activating TRPV3 receptors and inhibiting TRPA1, initially stimulating and then desensitizing pain receptors. A 2014 human study (Kotaka et al.) demonstrated that topical camphor application induced both cold and warm sensations and measurably increased blood flow in skin and muscle, supporting its traditional use for circulation. Research suggests camphor supports relief from muscle tension and soreness through TRPV1 desensitization and TRPA1 blockade in sensory nerves, reducing pain perception. It is a common ingredient in OTC topical analgesics indicated for minor backache and musculoskeletal discomfort. Traditionally, camphor has been used in topical applications for muscle cramps and sprains — the PMC 2025 comprehensive review explicitly documents camphor preparations for sprains, strains, and minor injuries.

pure Wintergreen leaf oil

Wintergreen (Gaultheria procumbens) is a perennial shrub native to northeastern North America, with a long history of use among the Chipewyan, Iroquois, Menominee, and other Native American peoples for rheumatic conditions, headaches, and muscular discomfort. The essential oil is dominated by methyl salicylate (approximately 98–99%), a compound structurally related to aspirin that acts as a counterirritant and rubefacient. Methyl salicylate is FDA-recognized as a topical counterirritant analgesic for muscle soreness. A 2010 randomized controlled trial (n=208) found that a methyl salicylate/menthol patch provided significantly greater pain relief for muscle strain compared to placebo (p=0.005), and a large Phase IV real-world trial (n=3,515) showed significant soft tissue pain relief. Research suggests Wintergreen's active glycoside gaultherin and its polyphenolic compounds also demonstrate anti-inflammatory activity in vitro and ex vivo, inhibiting NF-κB, COX-2, and pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α. Wintergreen is traditionally used for sprains and was historically applied externally to treat both musculoskeletal and neurological discomfort.

pure Eucalyptus leaf oil

Eucalyptus oil, derived from the leaves of Eucalyptus species in the family Myrtaceae, has been used by Aboriginal Australians for over 60,000 years to treat respiratory conditions and body aches. Its principal bioactive compound, 1,8-cineole (eucalyptol), has documented anti-inflammatory properties — research shows it attenuates pro-inflammatory mediators including TNF-α, IL-1β, and IL-6 through downregulation of NF-κB and p38 MAPK pathways. Studies suggest Eucalyptus oil supports muscle comfort: an RCT in patients undergoing total knee replacement found inhaled Eucalyptus oil significantly reduced pain scores and inflammatory markers versus control, and electromyography studies have documented direct myorelaxant effects. The compound also demonstrates mucolytic and bronchodilatory activities. In a study of patients with rheumatoid arthritis, inhaled Eucalyptus oil was associated with significant pain reduction compared to the control group, suggesting broader analgesic potential.

pure Lavender flower oil

Lavender (Lavandula angustifolia) is a perennial sub-shrub native to the Mediterranean, with a medicinal history stretching from ancient Egypt and Rome through medieval Europe. Its essential oil contains over 170 volatile organic compounds, dominated by linalool and linalyl acetate. Research has established that linalool potentiates GABAergic currents, modulating GABA-A receptors, while linalyl acetate antagonizes NMDA receptors and enhances GABA action — providing a mechanistic basis for Lavender's well-documented calming effects. A meta-analysis of 65 RCTs found inhaled Lavender significantly reduced anxiety (Hedges g = −0.73), and multiple clinical trials show oral Lavender oil preparation (Silexan, 80 mg/day) is comparable to lorazepam and paroxetine for anxiety symptoms. Lavender is approved by the German Commission E for sleep disturbances associated with anxiety, and a 2026 meta-analysis of 11 RCTs (628 participants) found its sleep-enhancing effect was significant. Traditionally, Lavender essential oil has been used in European aromatherapy and herbal medicine for muscle tension and spasm, with preclinical studies supporting analgesic and antispasmodic activity.

pure Clove oil

Clove (Syzygium aromaticum) is an evergreen tree native to the Maluku Islands of Indonesia, with a spice-trade history dating back to 300 B.C. The essential oil is dominated by eugenol (70–90%), a phenylpropanoid with well-researched analgesic, anti-inflammatory, and antioxidant properties. Eugenol is a clinically recognized analgesic — a systematic review of 21 clinical studies identified it as having the most consistent evidence among phytotherapeutic agents for dental pain management. It blocks voltage-gated sodium channels and TRPV1 pain receptors, and a human RCT confirmed eugenol paste outperformed alternatives for post-surgical dental pain and healing. Research also demonstrates that eugenol inhibits 5-lipoxygenase enzyme through a non-competitive mechanism and suppresses the NF-κB inflammatory pathway, contributing to its broad anti-inflammatory profile. In traditional Chinese medicine, Clove has been used for digestive complaints and respiratory congestion, while Ayurveda values it for improving circulation and clearing stagnation.
