Materials
- St John’s wort flowers
Method
- In order to make a 1:2 oil, weigh the flowers and use double the amount of oil to flowers (eg. 50 g:100 ml)
- Place the flowers in a kilner jar and cover with the carrier oil ensuring the flowers are fully submerged.
- Place the oil on a sunny windowsill or in the garden for between 2–4 weeks to macerate in the sun.
- Strain the mixture through a muslin cloth and store in labelled bottles.
- Including some unopened flower buds along with the flowers and tops will add to the medicinal benefit as the buds contain the highest levels of hypericin.
- Use fresh plant rather than dried plant material for the most potent maceration.
