St John's wort is often called 'the medicinal plant of the 21st century'. Since ancient times, it has been used to treat emotional problems and nervousness. It plays a particularly important role in traditional folk medicine, because it's rich in medicinal compounds and has proved effective in studies, especially for depression, anxiety and sleep problems.¹ It's best known, however, for its mood-lifting effect and its support for emotional balance.
Because it has so many uses, St John's wort is becoming increasingly popular in the UK too.
But which St John's wort is right for you?
There are countless St John's wort supplements on the market, but not all of them are effective.
St John's wort: the medicinal plant of the 21st century
St John's wort (Hypericum perforatum) is a widespread medicinal plant that originally comes from Europe and Asia.
In the Middle Ages in particular, it was used in monasteries, mainly to treat emotional symptoms, nervousness and sleep problems. Known for its many health uses, it's now cultivated and used in many parts of the world.
The plant grows upright and has distinctive long, green leaves. These leaves are covered in tiny translucent dots, glands that release an essential oil when you touch them.
What makes St John's wort so special?
The medicinal properties of St John's wort are concentrated mainly in the flowers and leaves, which contain a wide range of bioactive compounds. The most important active ingredient is hypericin, a flavonoid that various studies have linked to antidepressant and anti-anxiety effects.²
St John's wort also contains other valuable compounds such as hyperforin, flavonoids (e.g. quercetin), tannins and essential oils, which have antioxidant and anti-inflammatory properties. These compounds contribute to the effect of St John's wort by stabilising the nervous system, lifting your mood and improving your general wellbeing.
The mood-lifting properties of St John's wort come from its flowers and leaves, which are rich in hypericin and hyperforin: two valuable plant compounds with a positive effect on the nervous system.

Possible side effects include stomach and bowel problems or dizziness, especially in sensitive people or at very high doses. St John's wort can also make your skin more sensitive to light, so take care in strong sunshine.

Organic St John's wort capsules offer clear advantages over conventional products:

✓ Higher active ingredient content: thanks to natural cultivation under ideal conditions, organic St John's wort often contains more hypericins and flavonoids, which are key to its mood-lifting effect.
✓ No unnecessary additives: while conventional St John's wort capsules often contain fillers, artificial colourings or anti-caking agents, organic products contain only the plant itself, with no synthetic additives.
✓ Better tolerability: without synthetic residues or genetically modified ingredients, organic St John's wort capsules are especially gentle on the stomach and well tolerated.
✓ Sustainability: organic farming protects soil, water and biodiversity, so choosing organic means higher quality and also helps protect the environment.

Schoenenberger St John's Wort
by Schoenenberger
Pros
- 100% natural juice
- Made from fresh St John's wort leaves
- Easy to use
- Free from alcohol, lactose and gluten
- Combines well with other foods
- Suitable for vegetarians and vegans
- No artificial additives
- GMO-free
Cons
- Less precise dosing
- Can cause stomach irritation if taken on an empty stomach
- Short shelf life once opened
Verdict
Schoenenberger St John's Wort Juice offers a natural way to support mental wellbeing. The juice is made from fresh St John's wort leaves, and this natural, pure preparation supports its effectiveness. The liquid form is practical if you prefer juice, but dosing is less precise than with capsules or tablets.
Another drawback of this liquid form is its relatively short shelf life once the bottle has been opened, which means you need to use it up within a short time. In some cases, the juice can also irritate the stomach if you take it on an empty stomach.
Users are fairly positive about Schoenenberger St John's Wort Juice. Taking it relieves symptoms such as sleep problems and restlessness, and it is well tolerated. However, users with chronic symptoms often find the effect unsatisfactory, and some customers criticise the taste and, in a few cases, the tolerability. One pack contains 200 ml.
St John's wort as a mood lifter
St John's wort is best known for its positive effect on mental health. The plant has been used for centuries to treat low mood, inner restlessness and emotional exhaustion. This effect comes from the plant compounds hypericin and hyperforin, which influence the metabolism of the neurotransmitters serotonin, dopamine and noradrenaline. These chemical messengers are particularly important for regulating mood, motivation and energy. Taking St John's wort regularly can help stabilise your mood, ease anxiety and improve your general wellbeing.
Relaxation for body and mind
As well as lifting your mood, St John's wort has calming properties that are particularly helpful for stress, nervousness and sleep problems. During hectic or stressful times, the plant can help stabilise the nervous system and reduce inner restlessness.⁷ The calming effects come from the flavonoids and essential oils it contains, which have a relaxing effect on the body. Many people say St John's wort helps them fall asleep faster and sleep through the night, because it calms the mind and has a balancing effect on the autonomic nervous system.
Physical wellbeing always goes hand in hand with mental wellbeing. St John's wort helps you face the day with renewed energy and a brighter mood.
Anti-inflammatory: protection for cells and tissue
St John's wort doesn't only act on the mind: it can also have a therapeutic effect on the body. The plant contains numerous antioxidants, including flavonoids and tannins, which neutralise free radicals and so reduce oxidative stress. This protective mechanism helps prevent cell damage and strengthen the immune system. St John's wort also has anti-inflammatory properties and can be used both internally and externally. It's traditionally used to treat skin irritation, minor burns and wounds, as it supports wound healing and soothes inflammation in the tissue.
Our verdict: St John's wort for everyday wellbeing
St John's wort is one of the most valuable medicinal plants when it comes to supporting emotional balance and general wellbeing. Its mood-lifting, calming and anti-inflammatory properties make it a popular natural alternative to synthetic medicines. It can help ease low mood, improve sleep and protect the body from oxidative stress. If you'd like to benefit from its positive effects, choose high-quality products and ask your doctor if you're unsure. Used correctly, St John's wort can be a valuable support for body and mind and help bring more inner balance to your everyday life.
