Hypericum perfoliatum aka St John’s Wort

This amazing plant serves us well both as a homeopathic remedy and an herb. You will find it used as a homeopathic remedy in several of our WHITE TUI remedies.  St John’s Wort is known as ‘the flower of light’ – its bright yellow flowers symbolizing the sun which casts out evil. It is also under the sign of Leo.

As an Herb:

The leaves and petals have characteristic oil glands, which give hypericums their aroma and colour. The leaves, when held up to the sunlight, have little perforations in them; this added to the magical association (the ancient practice of the use of pins to poke in dolls) and the yellow flowers when placed in water, gave up a dark red tincture which looks like blood. It is also a plant closely associated with the ‘Little People” or Fairy Folk – powerful beings who lived in the Underworld, known by both Europeans and the Native American Indians.


As Hypericum is invasive it is best grown in an area on its own or in a tub or pot. It is considered a noxious weed in NZ because it can cause sensitivity in sheep.

It grows easily from root cuttings or seed and prefers sunny, well-drained, chalky soil.

Case Study:

A 6 y.o.Rottweiler bitch diagnosed with osteosarcoma in her ® hind leg.

Because of the nature of the cancer and affirmation that it had not spread it was decided to amputate the leg. Together with other herbs, homeopathics, and very tidy surgery, the dog managed very well but seemed to be troubled by the surgical site and would swing her head around and glare at it.

It eventually dawned on the owner that she was experiencing phantom limb pain. Homeopathic Hypericum 200c was given twice daily for 7 days and then reduced to daily for a month. No more problems.
