If you lie awake with your mind running through tomorrow's list, you are not alone. Insomnia is one of the most common reasons people look for natural remedies and one of the oldest answers comes from a small purple flower.
What violet leaf oil is
Violet leaf oil is steam-distilled from the heart-shaped leaves of sweet violet (Viola odorata). It is a pure, concentrated green oil with a fresh, earthy scent. It is different from the traditional "violet oil" of Persian medicine, which was made by soaking violet in sesame or almond oil, but both come from the same plant and the same healing tradition.
Ibn al-Qayyim described the essence of violet as a remedy that "helps relieve hot headaches and brings sleep to the eyes" and called it a massage for the brain. In the Unani tradition, violet is cooling and moistening, the opposite of the hot, dry, overactive state linked with racing thoughts, irritability and sleepless nights.
What the sleep research found
The trials so far have used the traditional infused violet oil, so they tell us what this plant can do rather than testing our leaf oil directly.
In a 2018 double-blind trial, 75 adults with chronic insomnia used violet oil, almond oil or a placebo every night for a month. Violet oil improved sleep quality more than both and no serious side effects were reported (Journal of Ethnopharmacology, 2018).
In 2022 a team of researchers pooled five trials with 224 people with chronic insomnia. Compared with placebo, violet significantly improved overall sleep quality, how long people slept and how severe their insomnia was. It did not make a clear difference to how quickly people fell asleep, so it seems to help most with the depth and length of sleep (Huang et al., Frontiers in Neurology, 2022).
Violet and a restless mind
Large human trials on violet for anxiety have not been done yet. Early laboratory studies have found calming and anti-anxiety effects from violet oil (Asian Journal of Pharmaceutical Research and Health Care), which fits with how Persian physicians used it. For many people anxiety and poor sleep are the same problem seen from two sides and a calmer mind at night is often the first thing they notice.
A simple evening routine
- An hour before bed: put your phone away and dim the lights.
- In bed: put a quarter to half a dropper of violet leaf oil onto the centre of your scalp and breathe in deeply.
- Then: rub any leftover oil across your chest, temples and behind your ears.
- Give it time: use it every night for at least two to four weeks.
Safety
Violet leaf oil is for external use. Patch test first if you have sensitive skin. Speak to your doctor if you are pregnant, breastfeeding or taking medication for sleep or anxiety.
