Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Antidiarrhoeal  Antirheumatic  Astringent  Diuretic  Homeopathy  Vulnerary

Herb Robert is little used in modern herbalism, but is occasionally employed as an astringent to halt bleeding, treat diarrhoea etc in much the same way as G. maculatum[254]. The leaves are antirheumatic, astringent, mildly diuretic and vulnerary[7, 9, 21, 222, 238]. Modern research has shown that the leaves can lower blood sugar levels and so it can be useful in the treatment of diabetes[244]. An infusion of the leaves is used in the treatment of bleeding, stomach ailments, kidney infections, jaundice etc[222]. Externally, a wash or poultice is applied to swollen and painful breasts[222], rheumatic joints[7], bruises, bleeding etc[9]. It is best to use the entire plant, including the roots[9]. The plant can be harvested at any time from late spring to early autumn and is usually used fresh[9, 238]. A homeopathic remedy is made from the plant[9]. Details of uses are not given in this report[K].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

It is fascinating to discover that the foxy smell of Herb Robert has the effect of repelling rabbits. We have, perhaps insanely, tried to combine a small courtyard garden with pet rabbits for the past nine years and I have indeed noticed that the things I've planted in containers where Herb Robert has seeded itself, have been left in relative peace. Every other container and its contents has been comprehensively raided sooner or later by the rabbits - no matter how inaccessible I thought they were - and that included plants which rabbits are supposed not to like such as lavender and thyme which they bit into lots of little pieces just to exercise their teeth I think. I'm now going to study this phenomenon more closely and experiment with deliberately ring fencing precious plants with Herb Robert. It arrived by itself and I always liked it.

Fine native in Europe, Asia. Horrible noxious weed in the northern parts of the U.S./southern Canada. Some States claim it's native (Maryland & Wisconsin), I doubt they have evidence of this. It's introduced from Eurasia. I can smell it's horrid odor at least six feet away. Like a petro-chemical factory, totally nauseating. It is my most dreaded weed here in western Washington, almost worse than creeping buttercup (R. repens). But a greater threat to woodland ecology than buttercup.

I have been led to understand that herb robert is a highly medicinal plant when eaten on a daily basis in salads in small portions. I have heard it has anticarcinogenic qualities. Has anyone heard simelar acounts ?

Hello I am trying very hard to get this tea, Geranium Robertianum, and I cannot find it anywhere. Can someone help me to get it? I need it ASAP Thank you in advance for your help Sincerely Lucy Icleanu 8397 Langdon St, Philadelphia, PA 19090 Ph# 215-722-0960 Cel# 215-349-0310 [email protected]

I found this plant volunteering in a plant that recently came to Southern California from Northern California. It has since come up in several pots in my garden. I had a hunch and looked it and up and it is listed as an invasive species. Comment from Steve above confirms that view.   Jul 31 2014 12:00AM
