St John’s wort, Hypericum Perforatum or Kantarion
  • Post author:

The old folks always say “The cure is for free, all you need to do is find it.”
We have this remarkable herb at our home every winter, every month, every day. No matter as tea or as oil, St John’s wort is a magnificent medicinal plant.
The traditional name for it in my country is Kantarion, and we have plenty of it.

If this plant exists in your place, you should make the most of it because it has so many healing properties and can help you significantly improve your health. I summarize everything you should know about Hypericum perforatum or St John’s wort below.

What Is St John’s Wort?

The yellow St. John’s wort is a long-stemmed vegetable plant, 30-100 cm in height. It can be found on the edges of oak forests, pastures, at the foot of mountains, and in the surrounding meadows.

On Latin, Hypericum Perforatum was named after the Greek sun-god Hyperion.
It blooms all summer long, from late May until early September. The top of the herb and flower is picked.

It is rich in essential oils, iron, tannin, flavonoids, and hypericin which gives it a red oil color.
It is widely used in folk medicine because of its antibacterial, antiviral, and antimycotic properties.

It is one of 5 herbs used to improve mental health and is proven to have a positive effect on a mental illness such as depression. It is effective for mild to moderate depression. There is evidence about short-terms treatment, but there aren’t many long-term human studies especially for the connection between anxiety reduction and St. John’s wort.

The oil from this yellow herb is used for wounds and scars. Be careful on sunlight, the skin is more sensitive with this oil on it.

In some countries, St. John’s wort is available only with a prescription. And in France, you can’t find products with this herb because sometimes it can cause serious interactions with some medications.

How Can We Use Hypericum Perforatum?

We can use it for St. John’s wort like tea.

When I’m preparing it for myself, I put a few flowers (not too much because the natural homemade tea is stronger than that you can find it in a store) in boiling water. Still, find your best ratio and use it accordingly. Usually, the quantity of flowers required is about one teaspoon of 200 ml of boiled water.

I drink one cup of tea, often mixed with other tea like basil, elderberry flower or thyme before going to bed.

St. John’s Wort Oil Homemade Recipe

This is how my grandmother prepares homemade St. John’s wort oil.


  • 1.5L olive oil
  • Flowers to fill half bottle of 1.5L


  1. Take a clean, sterilized 1.5-liter glass bottle, and fill half of it with flowers. And then fill the bottle with olive oil.
  2. Close it and place it on sunlight for 40 days. The temperature in our country in the summer is from 30 to 40 °C, I guess that should be the right temperature.
  3. After 40 days move it inside and leave it to rest for 14 days.
  4. On the 15th day, drain it through gauze is another clear glass bottle and keep it on temperature between 18 – 25°C.


The best time to prepare is in the summer when the flowers are ready and the temperatures are high.

If you prepare it right and keep it at the right temperature, you can use it for a long time. (This summer, I found a bottle of St. John’s wort oil prepared 20 years ago. And it was fine, without any strange smell or color.)
