The Olfactory Training Kit is a medical-grade rehabilitation tool designed to stimulate neuroplasticity and help restore your sense of smell. Based on the clinically validated Hummel Protocol, this kit provides the precise concentrations of essential oils required for effective olfactory training.
Clinically indicated for post-viral anosmia, parosmia, and hyposmia — including smell loss following COVID-19.
The Science of Neuroplasticity
Olfactory training works by repeatedly exposing the olfactory receptors to four specific odour categories: floral, fruity, spicy, and resinous. This targeted stimulation encourages the brain to rebuild neural pathways — a process known as neuroplasticity. Clinical studies published in peer-reviewed journals confirm significant improvement after 12–24 weeks of consistent daily training.
What's Included
- 4 × 10ml Amber Glass Bottles — UV-protective glass preserves oil integrity
- 100% Pure Essential Oils — undiluted, single-origin botanical extracts
- The Clinical Protocol Guide — step-by-step instructions based on peer-reviewed research
The Protocol
Smell each of the four oils for 15–20 seconds, twice daily — morning and evening. Take a 10-second pause between each scent. Start your 3-month daily training today to regain your sense of smell. Clinical studies confirm significant improvement after 12–24 weeks of consistent practice.
Ingredients by Set
Set 1: Rose, Eucalyptus, Lemon, Clove
Set 2: Menthol, Thyme, Tangerine, Jasmine
Set 3: Violet, Peppermint, Bergamot, Ginger
Complete Kit: Sets 1 & 2 — 8 oils total. Recommended for comprehensive rehabilitation.

Medical Endorsement
"Olfactory training based on the Hummel Protocol is the gold standard non-pharmacological intervention for post-viral smell loss. I recommend structured training kits to my patients as the evidence for neuroplastic recovery is compelling."

What to Expect
Smell Recovery Timeline: What to Expect Week by Week
Based on clinical data from peer-reviewed olfactory rehabilitation studies
Week 1–2
Building the Habit
Establish your twice-daily routine. You may not notice changes yet — this is normal and expected.
Week 4–8
First Signals
Many patients report fleeting scent detection — brief moments where familiar smells begin to register again.
Week 12–24
Measurable Recovery
Clinical studies show 42% of patients achieve clinically significant improvement in olfactory function by this stage.
Month 6+
Continued Gains
Extended training shows further improvement. Many patients continue to see gains well beyond the initial 12-week period.
Results vary by individual. Based on data from Hummel et al. (2009), Damm et al. (2014). Consult your healthcare provider for personalised medical advice.

After 8 months of complete anosmia following COVID, I had given up hope. Started the training protocol with this kit and within 6 weeks I could detect the lemon and rose scents. Now at 4 months, my smell is approximately 70% recovered. This product gave me my life back.

Verified Purchase
My ENT recommended olfactory training and I found this kit. The quality of the oils is noticeably superior to what I tried from Amazon. The included protocol guide made the process straightforward. After 12 weeks of daily practice, I went from detecting 0 out of 4 scents to clearly identifying 3.
Post-Viral Smell Loss

Living with parosmia has been a nightmare. Everything smelled burnt or rotten. The structured training with this kit has significantly reduced the distortions. My morning coffee smells like coffee again for the first time in over a year. Giving 4 stars only because I wish the bottles were slightly larger.

The Hummel Protocol: Gold Standard in Olfactory Training
Developed by Prof. Thomas Hummel at TU Dresden, this protocol uses four specific scents (rose, eucalyptus, lemon, clove) for twice-daily exposure over a minimum of 12 weeks. It remains the most studied and validated approach to olfactory rehabilitation worldwide.
Common Questions
Frequently Asked Questions
Olfactory training is a clinically validated rehabilitation technique that uses repeated, deliberate exposure to specific scents to stimulate neuroplasticity in the olfactory system. By sniffing four distinct odors (rose, eucalyptus, lemon, and clove) twice daily for at least 12 weeks, you encourage the regeneration of olfactory receptor neurons and strengthen the neural pathways between your nose and brain. This protocol was developed by Prof. Thomas Hummel and has been validated in over 50 peer-reviewed studies.
Clinical studies show that most patients begin to notice improvements between 4 and 12 weeks of consistent daily training. However, significant recovery often continues for 6 to 12 months. The key factor is consistency: twice-daily training sessions of 20 seconds per scent. Research by Hummel et al. demonstrated that patients who trained for longer periods showed greater improvements, so we recommend committing to a minimum of 12 weeks before assessing your progress.
Olfactory training has shown efficacy for post-viral anosmia (including post-COVID smell loss), post-infectious olfactory dysfunction, parosmia (distorted smell), hyposmia (reduced smell), and age-related olfactory decline. It is the first-line non-pharmacological treatment recommended by the International Rhinology Guidelines. While results vary by individual and cause, the Hummel Protocol has the strongest evidence base of any olfactory rehabilitation method.
Our training kit uses pharmaceutical-grade essential oils at specific concentrations calibrated to the Hummel Protocol standard. Generic essential oils vary wildly in concentration, purity, and composition. Our oils are sourced from certified European suppliers, tested for purity, and formulated at the precise concentrations used in clinical trials. Additionally, our kit includes a structured training guide, progress tracking tools, and the complete four-scent protocol in medical-grade amber glass bottles designed to preserve oil integrity.
Open one bottle at a time and hold it approximately 2cm from your nose. Inhale gently for 20 seconds while actively thinking about the scent (this mental engagement is clinically important). Repeat with each of the four scents. Perform this routine twice daily, ideally morning and evening. Keep the bottles sealed between sessions to preserve potency. Each set provides approximately 12 weeks of training at the recommended usage rate.
