Medicinal Uses
Disclaimer
Antispasmodic; Blood purifier; Demulcent; Expectorant; Sedative; Stomachic.
The leaves and flowering tops are antiphlogistic, antispasmodic,
balsamic, demulcent, expectorant, sedative, stomachic and a vascular tonic[4,
7, 21, 46, 61, 207, 213]. Blood purifier[4]. The plant is applied externally
as a compress on inflamed or irritated areas of the skin[7, 257]. Used
internally, it slows down the heartbeat and reduces the stimulation of the
nerve endings in the air passages that causes coughing - it is therefore
extremely effective as a calming agent in the treatment of asthma[7].
The fluid extract is prepared by placing the freshly gathered leaves and
flowers in a small quantity of simmering water for about 15 minutes[213].
The plant is used to treat people affected by poison-ivy[213].
Other Uses
Dye; Hair; Parasiticide.
Yellow and green dyes are obtained from the flowering heads and
pods[168]. Aromatic.
A decoction of the roots has been used as a hair shampoo to kill lice[257].
Cultivation details
Succeeds in any well-drained soil in full sun[200]. Does well on dry
sandy banks and in poor soils[200].
Plants tend to concentrate selenium in the leaves and stems, this is
especially noticeable on soils that are relatively rich in that element[21].
Some authorities class this species as a synonym of G. camporum.
Propagation
Seed - sow autumn or spring in a cool greenhouse and only just cover
the seed. Prick out the plants into individual pots when they are large
enough to handle and plant them out into their permanent positions in early
summer.

Not so modern (1930's?) but lots of information, mainly temperate plants.
[7] Chiej. R. Encyclopaedia of Medicinal Plants. MacDonald 1984 ISBN 0-356-10541-5
Covers plants growing in Europe. Also gives other interesting information on the plants. Good photographs.
[21] Lust. J. The Herb Book. Bantam books 1983 ISBN 0-553-23827-2
Lots of information tightly crammed into a fairly small book.
[46] Uphof. J. C. Th. Dictionary of Economic Plants. Weinheim 1959
An excellent and very comprehensive guide but it only gives very short descriptions of the uses without any details of how to utilize the plants. Not for the casual reader.
[61] Usher. G. A Dictionary of Plants Used by Man. Constable 1974 ISBN 0094579202
Forget the sexist title, this is one of the best books on the subject. Lists a very extensive range of useful plants from around the world with very brief details of the uses. Not for the casual reader.
[168] Grae. I. Nature's Colors - Dyes from Plants. MacMillan Publishing Co. New York. 1974 ISBN 0-02-544950-8
A very good and readable book on dyeing.
[200] Huxley. A. The New RHS Dictionary of Gardening. 1992. MacMillan Press 1992 ISBN 0-333-47494-5
Excellent and very comprehensive, though it contains a number of silly mistakes. Readable yet also very detailed.
[207] Coffey. T. The History and Folklore of North American Wild Flowers. Facts on File. 1993 ISBN 0-8160-2624-6
A nice read, lots of information on plant uses.
[213] Weiner. M. A. Earth Medicine, Earth Food. Ballantine Books 1980 ISBN 0-449-90589-6
A nice book to read though it is difficult to look up individual plants since the book is divided into separate sections dealing with the different medicinal uses plus a section on edible plants. Common names are used instead of botanical.
[257] Moerman. D. Native American Ethnobotany Timber Press. Oregon. 1998 ISBN 0-88192-453-9
Very comprehensive but terse guide to the native uses of plants. Excellent bibliography, fully referenced to each plant, giving a pathway to further information. Not for the casual reader.
