If you look at them closely then you can see the tiny holes (the perforations) in the leaves. They are a key factor in identifying Hypericum perforatum.

*This is the method by which herbs infuse in oil over a period of weeks. If you are not in a rush then this is a lovely, minimal effort way to make them.


*TOP TIP: You will read and see lots of people telling you to leave the jar of infused oil on a sunny window ledge. DON’T do this! If you live in a country with very little sunshine it won’t get warm enough to extract your oil and it will not be very potent (and if you’ve made it with fresh herbs instead of drying them first, then your oil will go mouldy). If you live in a sunny country then it’s not a good idea either because prolonged exposure to the heat and light will cause your oil to go rancid (‘oxidise’ if you prefer the technical term). Instead, simply store your oil somewhere warm, dry and out of direct light. A dry cupboard is ideal.


*For full instructions on how to make the oil this way, or using the pan method shown in the video, scroll down to the RECIPE & EXTRACT DOCUMENTS below. There are options to read this on-screen or print off the PDF.

An Uplifting Herbal Tea Blend

St. John’s Wort is a really good addition to a tea blend to help to relax the nerves and ease stress. On its own, St John’s Wort can taste bitter. Combining it with other herbs that help to support and relax the nervous system can really improve and enhance the blend, including the taste. Lemon Balm adds a lovely, refreshing lemony flavour to the tea.

Here I combine it with other plants that soothe the nerves and (in my humble opinion) help to heal the body and soul.

*If you are on medication, pregnant, have an illness or medical condition REMEMBER to check the safety information on the herb data sheet to see if it’s safe for you to take St John’s Wort internally [herb data sheets for every featured plant, medical safety guidelines and foraging safety guidelines are available to everyone  enroled  in the course].

How to make an Infused Oil: the Jam Jar Method

Infused oils are therapeutic oils that can be used as a massage oil or added to creams and ointments. They can be made from fresh or dried herbs. In this video I have used fresh St John’s Wort to make the oil but, you could dry the St John’s Wort first and then use the dried herb to make your infused oil. Oils made with dried herbs do usually keep better because there isn’t any moisture left in the herbs before you add them to the oil.



Infused oils can be made from many herbs e.g. calendula, rosemary, plantain, comfrey, roses etc. In this recipe we are using St. John’s Wort.

Base oil/cooking oil

Use any cooking oil or base oil for the oil part of this recipe e.g. sunflower oil, safflower oil, grapeseed oil, sweet almond oil, apricot kernal oil, peach kernal oil etc. You could also use olive oil or rapeseed oil but I do find those quite smelly and that tends to over-power the subtle herbs. You could use coconut oil but keep in mind that it will be solid at room temperature so won’t work in the ointment recipe (although if it’s already solid at room temperature then there isn’t any need to turn it into a ointment!).

The Slow Jam Jar Method

  • Put the herbs (75g-100g fresh herb, or half weight for dried herbs) in a clean, dry jam jar and cover with 300ml of base oil (e.g. olive, sunflower etc.).
  • If you are using fresh herbs make sure that they are dry when you pick them.
  • Stir with knife to ensure that plant matter is completely covered with oil. Any air or moisture will cause mould to grow. Top up with additional oil if necessary (some herbs are very dry and will absorb lots of oil so you may need more oil than the volume listed in the recipe).
  • Cap and label with plant name and date.
  • Leave in the hot press/airing cupboard for 6 weeks.
  • Strain oil through muslin into a dark bottle.
  • Label with product name and date made.
  • Throw away plant material (it makes good compost).
  • Store out of direct sunlight.


Infused oils keep for up to 1 year. Make them every year.
