A traditional scented remedy that, in one standardized capsule form, has been tested the way a prescription drug is tested: it reduces anxiety, lifts low mood, and improves sleep by calming rather than sedating, without drowsiness, dependence or withdrawal. Inhaled, it eases anxiety and pain short-term. Manufacturer-funded trials and poor product authenticity are the weak links. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Alanine aminotransferase | 10–26 U/L (women), 10–33 U/L (men) | Linalool is cleared by the liver; establishes a baseline before combining with other liver-metabolised drugs |
| Aspartate aminotransferase | 10–26 U/L | Pairs with alanine aminotransferase to separate liver from muscle sources of enzyme rise |
| Seated office blood pressure | Below 120/80 mmHg | Tracks the pilot finding that inhaled lavender lowered pressure in adults with hypertension |
| Resting heart rate | 50–70 beats per minute | A simple proxy for the shift in autonomic arousal that the calming effect is meant to produce |
| Total testosterone (men) | 500–800 ng/dL | Addresses the anti-androgen activity seen in laboratory assays; relevant only with heavy sustained skin exposure |
| Estradiol (men) | 20–30 pg/mL | Addresses the oestrogen-like activity seen in the same assays; no adult case has been reported, so this is precautionary |
Cadence: Symptom scores repeated at two, six and ten weeks; weekly blood pressure through the first month where antihypertensive therapy is already in place; liver enzymes rechecked only if symptoms suggest a problem or interacting drugs are added; review every six to twelve months.
