Hypericum perforatum

St John's Wort

St John's wort is a sunny flowering herb traditionally valued to support mood, the nervous system and emotional resilience. A botanical profile from Amina's herb database.

St John's wort (Hypericum perforatum) is a cheerful yellow-flowered herb that Amina was delighted to find growing wild in the French Pyrenees on a mountain hike. Long woven into European folk tradition, it is one of the best known herbs for supporting emotional wellbeing and the nervous system.

Traditional and historical use

The aerial flowering parts are the portion traditionally used. Over the centuries St John's wort has been valued to:

  • Support a settled, balanced mood and emotional resilience
  • Support people who feel emotionally stretched or under sustained stress
  • Work with the nervous system as a traditional nervine tonic
  • Support restful sleep when the mind feels busy
  • Be applied topically in creams and oils, a long-standing folk preparation for the skin

In traditional practice the herb has also been associated with the bright energy of midsummer, often gathered around the longest days of the year, which is reflected in its common name.

How Amina considers it

In Amina's clinic, St John's wort is one of many herbs that may be considered for people navigating low mood, emotional stress or a nervous system under load. It is always chosen as part of an individualised plan that takes the whole person and their wider mood and stress picture into account, never as a one-size-fits-all remedy and never in isolation.

Safety and considerations

St John's wort is well known for interacting with a wide range of medications, including some antidepressants, the contraceptive pill, blood thinners and other prescription drugs, so it is not suitable for everyone. It can also increase sensitivity to sunlight in some people. Because of these interactions, it is especially important to seek advice from a qualified practitioner and to mention it to your doctor or pharmacist before use. You can always get in touch to talk through whether it suits your situation.
