St. John's is actually NOT one of my frequently used herbs and yet I do adore its sunshine radiance. I find its red color that it imbues into oils fascinating! Typically I use St. John's as an infused oil that I work into certain salves that I make. As far as its internal use, I tend to steer clear of it. The main reason for this is that in this day and age, so many people are using some sort of pharmaceutical and St. John's can have a powerful effect on the liver. It is an excellent choice when liver detoxing is what is intended, but can have detrimental effects on the health of people who rely on certain pharmaceuticals. It can purge them from the liver, and the result is that people are not getting the dosage of the medications that they might need.
Each. year I do make a small batch of infused olive oil from the flowers. I keep some tincture on hand, because it just seems like.....well......it grows here....Im an herbalist....and one day there may be a purpose for it. But for the. most part, I stick to it's external use.
OR.....I just go out and sit with it and admire it. It makes me happy. It reminds me of the sun, and in Maine this summer, we are not getting much sun at all.....so it's a happy little breathe of radiance to sit with this plant and take it in.
