“…Figure 4 highlights the total number of species correctly identified in relation to the contents of the packages and those that were not correctly identified. Martins et al (2015) analyzed samples of M. sylvestris or "mallow" available in dehydrated form in different Brazilian locations by using mass spectrometry and morphological analysis. They identified 50% of the samples as S. cordifolia.…”

“…They are, in the fact, Pelargonium graveolens, which are Geraniaceae, but very much resemble M. sylvestris. Romitelli and Martins (2013) and Martins et al (2015) report that the misuse of S. cordifolia can be dangerous to patients with cardiovascular problems, anxiety or behavioral disorders due to the presence of ephedrine, pseudoephedrine and alkaloids.…”

The Malva genus presents different species with therapeutic potential and inadequate consumption can occur due to the incorrect identification of the plant in the market. The objective of this study was to identify species of the Malva genus cultivated in the Western Mesoregion of Santa Catarina State-Southern Brazil, and to verify the conformity of products' labels marketed as dehydrated medicinal plants through the characteristics of the plant parts. The specimens were collected following an unsystematic procedure from households of ten municipalities. The material was identified with the help of specialized bibliography and a specialist. After, they were herborized and deposited in the herbaria of the State University of Santa Catarina (LUSC) and of the Botanical Garden Research Institute of Rio de Janeiro (RB). Five cultivated species of Malva were found (M. nicaeensis, M. parviflora, M. pseudolavatera, M. Sylvestris and M. verticillata). Whereas one species of the Geraniaceae family (Pelargonium graveolens) and three species of the Malvaceae family (Malva sylvestris, M. verticillata and Sida cordifolia) were found in the dehydrated packages. S. cordifolia species was present in 80% of the samples, with 65% of them marketed as M. sylvestris or under the common name of "mallow". Macroscopic images of the species and illustrations of the mericarps were made and an identification chart along with the morphological description for each species was elaborated based on the morphological results. Descriptions of labels for 60 samples were checked for the determination of the dehydrated Malva species marketed. Characteristics of parts of the plant in comparing them with the characteristics described in the specialized literature were performed. The target species of incorrect identifications in the analyzed packages was M. sylvestris.

“…Among dozens of plants popularly known as Malva (mallow), or that contain this word as part of their name, some stand out due to their use in folk medicine, especially Malva sylvestris (Malvaceae), known as common mallow, Sida cordifolia (Malvaceae) known as white mallow or silky white mallow, and Pelargonium graveolens (Geraniaceae) which, despite being from a different family, is known in Brazil as smelling mallow [ 9 ] but known as geranium elsewhere. In a recent study [ 9 ], it was observed that half of commercial samples purchased as M. sylvestris were actually S. cordifolia , while 25% of samples purchased as P. graveolens were, in fact, S. cordifolia . Since these plants are often mistaken or mislabeled, one for the other, and thus used for the same purposes, they were chosen to be compared with each other with regards to their anti-inflammatory properties.…”

The ability of plant extracts and preparations to reduce inflammation has been proven by different means in experimental models. Since inflammation enhances the release of specific mediators, inhibition of their production can be used to investigate the anti-inflammatory effect of plants widely used in folk medicine for this purpose. The study was performed for leaves and flowers of Malva sylvestris, and leaves of Sida cordifolia and Pelargonium graveolens. These are three plant species known in Brazil as Malva. The anti-inflammatory activity of extracts and fractions (hexane, chloroform, ethyl acetate, and residual) was evaluated by quantitation of prostaglandins (PG) PGE2, PGD2, PGF2α, and thromboxane B2 (the stable nonenzymatic product of TXA2) concentration in the supernatant of lipopolysaccharide (LPS)- induced RAW 264.7 cells. Inhibition of anti-inflammatory mediator release was observed for plants mainly in the crude extract, ethyl acetate fraction, and residual fraction. The results suggest superior activity of S. cordifolia, leading to significantly lower values of all mediators after treatment with its residual fraction, even at the lower concentration tested (10 μg/mL). M. sylvestris and P. graveolens showed similar results, such as the reduction of all mediators after treatment, with leaf crude extracts (50 μg/mL). These results suggest that the three species known as Malva have anti-inflammatory properties, S. cordifolia being the most potent.
