Viola tricolor
This monograph compiles 2 documented constituents, 6 pharmacological actions, 11 traditional / indicated uses, supported by 10 cited sources, drawn directly from the Omnia Sana plant database.
Key Constituents
Bioactive cyclic peptides shown to suppress over-active immune (T-cell) responses - the rationale for use in inflammatory skin disease; the cytotoxic cyclotides vitri A, varv A and varv E have been isolated from V. tricolor. Cyclotide-enriched preparations (including hot-water decoctions) reduce T-cell proliferation and macrophage cytokine output in vitro, of interest for inflammatory bowel disease.
Pharmacological Actions
Anti-inflammatory / immunomodulatory for chronic skin conditions - eczema, psoriasis, itching and scabs (traditional, supported by cyclotide research) - cyclotide-enriched V. tricolor preparations suppress T-cell proliferation and pro-inflammatory cytokine secretion in vitro; Soothes irritated skin (demulcent and anti-inflammatory)
Cytotoxic / antiproliferative against cancer cell lines in vitro (cyclotides vitri A, varv A and varv E)
Soothes irritated skin (demulcent and anti-inflammatory); Traditional demulcent / expectorant for cough, bronchitis and chest inflammation
Traditional demulcent / expectorant for cough, bronchitis and chest inflammation
Anti-inflammatory / immunomodulatory for chronic skin conditions - eczema, psoriasis, itching and scabs (traditional, supported by cyclotide research) - cyclotide-enriched V. tricolor preparations suppress T-cell proliferation and pro-inflammatory cytokine secretion in vitro

Regarded as safe in customary traditional use; because the extract suppresses immune-cell activity, there is a theoretical caution when taking immunosuppressant medicines.
Contains salicylates, so use caution if you are salicylate-sensitive; safety in pregnancy and breastfeeding is not established.
