Malva sylvestris L. - Malvaceae - common mallow, high mallow, tall mallow, cheeses,
Wilde Malve, Rosspappel, Große Käsepappel

Erect perennial herb, 0.30-1m tall, native to Eurasia; inflorescences erect, axillary, clusters; flowers bright pink, pale in the centre, with darker pink (violet) lines like rays from the centre; petals 15-30mm , sepals 5-7mm long.

M.sylvestris „…is among the oldest known cultivated plants and was already cultivated in ancient times as a vegetable and medicinal plant. Its German trivial name 'Käsepappel' has nothing to do with the poplar, but refers to the cheese loaf-like, mucilaginous fruits, from which was prepared 'Papp' (pap).“

The main acidic polysaccharide preparation isolated from the leaves of M.sylvestris L. var mauritiana Mill. is composed of l-rhamnose, d-galactose, d-galacturonic acid, and d-glucuronic acid in the molar ratio of 22:6:22:11, and contains 7.7% peptide. The substance showed considerable anticomplementary activity.

The leaves of M.sylvestris contain 8-hydroxyflavonoid glucuronides like gossypetin 3-glucoside-8-glucuronide and hypolaetin 4′-methyl ether 8-glucuronide, hypolaetin 8-glucuronide and isoscutellarein 8-glucuronide.

The dried leaves (Malvae folium) or flowers (Malvae flos) are used in folk medicine. „The main use of the herb is to treat mucosal irritations of the mouth and throat, that result in dry, irritating cough. It is also considered useful as a mild astringent to treat gastroenteritis. Traditionally it was used internally in case of bladder complaints and externally as a poultice for wounds.“
[Medicinal Plants of the World. Ben-Erik Van Wyk and Michael Wink, Pretoria 2004, 197]

From the aqueous extract of M.sylvestris, eleven compounds were isolated: 4-hydroxybenzoic acid, 4-methoxybenzoic acid, 4-hydroxy-3-methoxybenzoic acid, 4-hydroxycinnamic acid, ferulic acid, methyl 2-hydroxydihydrocinnamate, scopoletin, N-trans-feruloyl tyramine, a sesquiterpene, (3R,7E)-3-hydroxy-5,7-megastigmadien-9-one, and (10E,15Z)-9,12,13-trihydroxyoctadeca-10,15-dienoic acid.

M. sylvestris flower extract accelerated wound healing in rats. Extract-treated wounds showed increased well organized bands of collagen, more fibroblasts and few inflammatory cells. The extract effectively stimulated wound contraction as compared to control group and other groups. These findings support the plants traditional use.

malvidin-3-glucoside (oenin)

„Malva sylvestris has been used since ancient times for its emollient, laxative and anti-inflammatory properties, being extensively used as salads, soups and teas… The LC–MS analysis of the HE (hydroalcoholic extract) confirmed the presence of scopoletin, quercetin and malvidin 3-glucoside … Topical application of the HE reduced ear oedema, polymorphonuclear cells influx (myeloperoxydase activity and histological analysis) and interleukin-1β levels in the tissue. The topical application of the compound present in the HE, malvidin 3-glucoside was also able to inhibit ear oedema and leukocytes migration. The other tested compounds, scopoletin, quercetin and malvidin 3,5-glucoside were able to prevent the formation of oedema and cell infiltration, but with less effectiveness when compared to HE and malvidin 3-glucoside. Therefore, these results consistently support the notion that M. sylvestris leaves possesses topical anti-inflammatory activity, the compound malvidin 3-glucoside seems to be major responsible for this effect, with the participation of other anti-inflammatory compounds in the extract… M. sylvestris can be used as a future treatment to skin disorders.“
