Tansy (Tanacetum Vulgare)

The parts used are the leaves and flowers which contain the active ingredients sesquiterpene lactones, volatile oil and flavonoids.

Tansy

I was in two minds whether to write about Tansy from a safety point of view as I do not advise self medication with it as it is such a strong herb. But as we had been looking at it on the shingle beach and it is so pretty and very interesting I thought I would.

It is used as an “Emmenagogue” meaning it is used in the absence of menstruation to bring on and help regulate periods and to expel worms from the gut.

If you ever see an herb has the ability to expel worms you will know that it is a very strong herb and must not be experimented with.

The same action which helps expel worms from the body may also cause abortion so it absolutely must not be taken in pregnancy.

Herb Walk Around a Shingle Beach July 2011

We live in a newly developed area, called Sovereign Harbour, three miles outside Eastbourne in East Sussex. The area was a shingle beach known as The Crumbles and was one of very few shingle habitats left in the U.K.  I have met many people who remember The Crumbles as they were and describe to me a wild area with different plants and animals inhabiting it.

There are still five sites within the area available for development, which are as yet, un-built on, due to harbour residents campaign to prevent over-development of the land, but which will be built on in the future.

Lucky for us, these areas still have an interesting variety of plants growing on them and also make good dog walking areas. The main species of birds I have seen, apart form the gulls, are linnets, greenfinches, sparrows, blackbirds and starlings. Lots of rabbits and foxes and some hedgehogs which, sadly, I only know about when they get squished on the road

We are also surrounded by marshy areas, Down land and Weald, resulting in several distinct habitats within a few miles from our house.

I was particularly interested to see three plants growing on the shingle which look very similar but which it would be very dangerous to muddle up.

Ragwort grows on most waste ground. It has poisonous properties and will kill a horse if it eats it.

St. John’s Wort is a nervous system supporting and repairing herb with anti depressant and liver stimulating properties. St. John’s Wort can be photosensitising both taken internally and applied externally as an oil, so if you are taking St. John’s wort, care needs to be taken in bright sunlight.

Tansy puts on a fantastic show and is often cultivated in herbaceous borders for its bright yellow flat head flowers. It is used medicinally in very small amounts to tone the female reproductive system and to kill thread worm (don’t self medicate with tansy, you need to know exact doses and it can cause abortion)

Evening primrose:- the oil from the seed is high in Omega 6 and is said to help with PMT. I personally am not an evening primrose oil fan or advocate but the plant is very pretty.

The other plants we saw on this herb walk were

Centaury, astringent and toning for all mucous membranes.

Tormentil , astringent and toning for all mucous membranes

Yellow dock, digestive system and liver stimulant.

Goat’s rue, reduces blood sugar (don’t self medicate)

St. John’s wort, Centaury, Tormentil and Yellow dock will have their own write up in the Herbs and health section

There are many other plants growing on the shingle, not the least of which is a beautiful Bee orchid which grows in the spring and I have to confess I hope that the planning permission battles will continue for some time.
