Helps

What does Lavender (Silexan) help with? Lavender has been used around the Mediterranean for ages. Silexan is a lavender oil that comes in a capsule. It was made for calm and mood, not for scent or skin. Silexan has more human trial data for anxiety than most calming herbs. The notes in this file name trials, but do not record their size or dose. So each grade below rests on the trials as the file describes them. Anxiety that will not switch off, including diagnosed generalised anxiety Strong evidence — several randomised human trials in generalised anxiety. In more than one randomised trial, anxiety scores dropped in people taking Silexan. The drop was close to what low-dose anxiety drugs gave. Trials also reported no drowsiness and no sign of dependence. Evidence grade A · Traditional tier T0 Feeling jittery, on edge, or unable to wind down Good evidence — clinical trials that measured restlessness and tension. In clinical trials, people reported less restlessness and less nervous tension. The change built up over a few weeks. It did not act like a fast sedative. Evidence grade B · Traditional tier T0 Anxiety and low mood showing up together Good evidence — clinical trials in people with both sets of symptoms. In trials of people with both problems, mood scores and anxiety scores both improved. Lab work points to an effect on serotonin, a brain chemical tied to mood. That link is a proposed reason, not something shown in people. Evidence grade B · Traditional tier T0 Anxiety you feel in your body: tight chest, upset stomach, tense muscles Good evidence — trials that scored body symptoms as well as mental ones. In clinical trials, these body signs eased, not just the worry in the mind. The body scores moved along with the mental ones. Evidence grade B · Traditional tier T0 Trouble falling asleep when your mind will not stop Good evidence — sleep measures taken inside anxiety trials. In trials, people fell asleep more easily and rated their sleep as better. The gain was clearest when night-time worry was the cause. Sleep was tracked next to anxiety, not as the main target. Evidence grade B · Traditional tier T0 Feeling worn out by stress (neurasthenia) Early evidence — trial data in stress exhaustion, plus long use in European herbal practice. Trial data show less fatigue and less emotional burnout in people with this pattern. European herbal medicine lists it for this use. The human data here are thinner than for anxiety. Evidence grade C · Traditional tier T0 Mood swings and irritability around menopause Early evidence — early clinical studies only. Early clinical work points to less anxiety and less irritability in these years. Women also reported steadier mood. It is a non-hormone option, but the studies so far are few. Evidence grade C · Traditional tier T0 Support alongside care for post-traumatic stress Evidence doesn't support this — preliminary human data only. The evidence here is early and thin. Some reports point to a calmer feeling and less on-edge arousal. It has not been studied as care for PTSD on its own. Evidence grade D · Traditional tier T0 What Lavender (Silexan) has not been shown to do It has not been shown to calm you within minutes; in trials the change took a few weeks. It has not been shown to help insomnia that comes from a primary sleep disorder rather than worry. It has not been shown to stand alone as care for post-traumatic stress. Nothing on file tests it for hot flashes or other body signs of menopause. Nothing on file tests it for major depression on its own. How to read this: Grade A means steady results across randomised human trials. B means at least one good human trial. C means small or early human work. D means the human evidence is weak or mixed. Insufficient means no human study at all. This page reports what studies found. It is not medical advice, and it is not a claim that Silexan treats any illness. Talk with your own clinician before you change anything, above all if you already t
