Saponaria officinalis - L.
                 
Common Name Soapwort, Bouncingbet
Family Caryophyllaceae
USDA hardiness 4-8
Known Hazards The plant contains saponins[13]. Although toxic, these substances are very poorly absorbed by the body and so tend to pass through without causing harm. They are also broken down by thorough cooking. Saponins are found in many plants, including several that are often used for food, such as certain beans. It is advisable not to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish[K]. Do not use for more than 2 weeks. Avoid during pregnancy.
Habitats Fields, roadsides and along the banks of streams[7].
Range Europe, including Britain, from Scandanavia south and east to Spain and temperate Asia.

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.

Alterative;  Antipruritic;  Antirheumatic;  Antiscrophulatic;  Cholagogue;  Cytotoxic;  Depurative;  Diaphoretic;  
Diuretic;  Expectorant;  Purgative;  Skin;  Sternutatory;  Tonic.

Soapwort's main medicinal use is as an expectorant. Its strongly irritant action within the gut is thought to stimulate the cough reflex and increase the production of a more fluid mucus within the respiratory passages[254]. The whole plant, but especially the root, is alterative, antiscrophulatic, cholagogue, depurative, diaphoretic, mildly diuretic, expectorant, purgative, sternutatory and tonic[4, 7, 9, 13, 21, 218]. A decoction of the whole plant can be applied externally to treat itchy skin[4, 201, 238]. The plant has proved of use in the treatment of jaundice and other visceral obstructions[4], but is rarely used internally in modern herbalism due to its irritant effect on the digestive system[238]. When taken in excess, it destroys red blood cells and causes paralysis of the vasomotor centre[238]. See also the notes above on toxicity[4, 7]. The root is harvested in the spring and can be dried for later use[7]. One of the saponins in this plant is proving of interest in the treatment of cancer, it is cytotoxic to the Walker Carcinoma in vitro[218]. The German Commission E Monographs, a therapeutic guide to herbal medicine, approve Saponaria officinalis Soapwort. Bouncingbet for coughs/bronchitis (see [302] for critics of commission E).
Other Uses
Soap.

A soap can be obtained by boiling the whole plant (but especially the root) in water[6, 13]. It is a gentle effective cleaner[7, 95], used especially on delicate fabrics that can be harmed by modern synthetic soaps (it has been used to clean the Bayeaux tapestry). It effects a lustre in the fabric[171]. The best soap is obtained by infusing the plant in warm water[169]. The roots can be dried and stored for later use[169]. The plant is sometimes recommended as a hair shampoo, though it can cause eye irritations[238]. The plant spreads vigorously and can be used as a ground cover when planted about 1 metre apart each way[208].
Cultivation details
Landscape Uses:Border, Rock garden. Succeeds in any moderately fertile well-drained soil in sun or semi-shade[200]. Prefers a neutral to alkaline soil[238]. Hardy to about -20°c[187]. A very ornamental plant[1], soapwort is often grown in the herb garden and is sometimes cultivated for the soap that can be obtained from the roots. There are some named forms, usually with double flowers, that have been selected for their ornamental value[187]. Plants can be very invasive when grown in good conditions[K]. Soapwort should not be grown next to a pond with amphibians or fish in it since if the plant trails into the water it can cause poisoning[238]. The flowers are slightly scented with a sweet aroma that has an undertone of clove[245]. Hybridizes with other members of this genus[200]. A good moth plant[13, 24]. Special Features:Edible, Fragrant foliage, Not North American native, Invasive, Naturalizing, Attracts butterflies, Suitable for cut flowers, Fragrant flowers.
Propagation
Seed - best if given a short cold stratification. Sow autumn or late winter in a cold frame. The seed usually germinates within 4 weeks. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in early summer. Division in spring or autumn. Very easy, it can be successfully done at any time in the growing season if the plants are kept moist until they are re-established. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.

Very invasive. In my garden it ropagated itself through rizmos to neaby rose garden coming out right near the rose canes. I cannot fine any information about getting rid of the deep in ground roors & rizmos. Nurseries should warn clearly about its invasive nature. A statement like 'somewhat invasive' is not helpful.

Horrendously invasive!! Plant only if you have acres of poor soil where not a lot else will grow!I suppose if you were into natural soaps or living in an iron age settlement and you were the owner of a celtic laundrette then there would be a use for this plant!! It is pretty and attractive enmasse but be advised that the deep-rooted ,adventurous rizomes are as bad as couch grass!

Bremness (Eyewitness Handbook Herbs) says the flowers can be added to salads, but also says they are used to give a head to beer which suggests bubbly toxic (apparently mildly in moderate does) saponins. Bremnes is rarely wrong but it is odd virtually none else lists this use.
