Cholagogue  Demulcent  Diuretic  Laxative  Refrigerant  Urinary  Vulnerary

Pellitory of the wall has been valued for over 2,000 years for its diuretic action, as a soother of chronic coughs and as a balm for wounds and burns[254]. In European herbal medicine it is regarded as having a restorative action on the kidneys, supporting and strengthening their function[254]. The whole herb, gathered when in flower, is cholagogue, slightly demulcent, diuretic, laxative, refrigerant and vulnerary[4, 7, 61, 165, 238]. It is an efficacious remedy for kidney and bladder stones and other complaints of the urinary system such as cystitis and nephritis[4, 238, 254]. It should not be prescribed to people with hay fever or other allergic conditions[238]. The leaves can be usefully employed externally as a poultice on wounds etc[4]. They have a soothing effect on simple burns and scalds[7]. The plant is harvested when flowering and can be used fresh or dried[238].

Plant Propagation

Seed - sow spring or autumn in a cold frame. Prick out the seedling when they are large enough to handle and plant them out in the summer. If you have sufficient seed then it can be sown in situ in autumn or spring. Division in spring. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

i would really appreciatte it if someone could help me, about where, all over the world, can I buy Parietaria judaica seeds? Thank you very much. JUAN. SPAIN.

Chiltern Seeds might sell Parietaria judaica? Seems to grow well in the Brighton area of East Sussex, England. It certainly seems to like walls, fences etc. I will be trying some as food (not great at growing veg) and would appreciate any recipes.

I don't believe P. judaica is really a synonym for P. officinalis, unless something has changed. This 1968 article describes the differences: http://www.watsonia.org.uk/Wats6p365.pdf (PDF) P. judaica (known as Asthma Weed in Australia) in particular appears to be associated with asthma and skin allergies. There's video of someone putting on a mask and gloves to remove it here: http://sydneyweeds.org.au/digging-out-asthma-weed/ A scholar.google.com search comes up with references to hayfever and both species. I've eaten either P. officinalis or P. judaica (I'm not sure which) without ill effect. However because some people have allergies care should be taken.

Parietaria judaica (L., 1759) synoms: Parietaria diffusa (Mert& Koch, 1823, Parietaria ramiflora (Moensch, 1794) There is so much confusion regarding these two species, see Townsend C.C, Parietaria officinalis and P. judaica, Watsonia, 6 (6), 1968, I found it exhaustive. Parietaria j. is a spontaneous weed that grows even by cuttings. The seed are very littles and is difficult to obtain experimentaly a good result by seeding. P. judaica has a very high content in phenolics that are antioxidant products anyway you must check your tollerence as both species are allergenic (pollen and hairs) A simple way is to rub a leave on your arm and wait if it become reddened.
