Wild pansy: benefits, dosage, contraindications

Mis à jour le

The wild pansy, also called "field pansy", "tricolor pansy" or "Herb of the Trinity", is an annual herbaceous plant that reaches on average 30 cm, with oval, lobed leaves and tricolored flowers. Their color makes it possible to distinguish the variety arvensis, whose four upper petals are yellowish-white, from the variety vulgaris, whose four upper petals are violet. It is native to Europe, North Africa and the temperate regions of Asia. It grows both in mountainous areas and in coastal regions. The parts used therapeutically are the aerial parts. Wild pansy is composed of flavonoids (up to 2.9%) such as vitexin, rutin, violanthin (up to 0.8%), phenolic acids (up to 0.5%), mainly salicylic acid and its derivatives methyl salicylate and violutin, mucilage polysaccharides, 16-24% in V. arvensis and 8-12% in V. tricolor, tannins, carotenoids (zeaxanthin...) and cyclotides (around 0.02%): these are macrocyclic peptides. Traditionally, wild pansy is used for its purifying action and in the treatment of skin conditions such as eczema, acne, seborrhea, as well as infant diaper rash. It is also used as an expectorant in respiratory conditions.

Indications

Scoring methodology

EFSA approval.

Several randomized, double-blind, controlled clinical trials (> 2), including a significant number of patients (>100), with consistently positive conclusions for the indication.

One or more randomized studies, or several cohorts or epidemiological studies, with positive conclusions for the indication.
Clinical studies exist but are uncontrolled, with conclusions that may be positive or conflicting.
No clinical studies to date that can demonstrate the indication.


Eczema
✪✪✪✪✪

Preliminary clinical research shows that application of an ointment containing 5% of each extract of wild pansy, gotu kola and Oregon grape twice a day for 4 weeks does not improve eczema compared with a base cream. However, patients with eczema on skin exposed to cold may experience some improvement.

Chronic obstructive pulmonary disease
✪✪✪✪✪

Preliminary clinical research in men aged 40 to 70 with a history of smoking and stage 2 chronic obstructive pulmonary disease (COPD) shows that taking a combination of 165 mg wild pansy, 165 mg calendula flowers and 165 mg elderberry, at a dose of 3 capsules per day for 6 months, moderately improves dyspnea, cough and sputum production compared with placebo. However, the number of COPD exacerbations per month does not appear to be changed.

Properties


Antioxidant

full-leaffull-leaffull-leafempty-leaf

Because of its content of flavonoids and other phenolic compounds, wild pansy may be a source of natural antioxidant. In vitro, a hydroalcoholic extract of fresh wild pansy leaves or flowers has been shown to possess antioxidant activity. Polar components have greater activity; among these are flavonoids such as rutin and violanthine.


Anti-inflammatory

Wild pansy is traditionally used for inflammatory pulmonary and skin conditions. In vitro, wild pansy extract inhibited the secretion of various inflammatory cytokines, resulting in inhibition of the proliferation of activated lymphocytes. The bioactive constituents appeared to be cyclotides.

In a rat model of eczema, an improvement in skin disorders was observed after adding fresh wild pansies to the diet for 2 months, compared with a control group.

Antimicrobial

Some trials have evaluated the antimicrobial properties of different preparations of Viola tricolor. The most effective preparations are aqueous and alcoholic extracts. They have a significant effect on Gram-positive bacteria such as Staphylococcus aureus, S. epidermidis and on the yeast Candida albicans. The least effective preparations are those with high molecular selectivity, which suggests a synergistic action of the different components present in the other extracts. Cyclic peptides or cyclotides are notably responsible for this effect.

Diuretic

A study showed that administration of a mother tincture of wild pansy to rats has a moderate diuretic effect. Indeed, diuresis was increased by about 10% compared with the control group, Na+ excretion by 18% and K+ excretion by 36%.


Safe dosage

Adult: 1.5 g - 4 g (tisane/tea/infusion, dry extract)

- Internal use Adults: 1.5-4 g of the medicinal product as an infusion three times a day; fluid extract ([1:1], ethanol 25%) 2-4 ml three times a day; dry extract (6:1), 2-4 g per day. - External use 3-4 g of the medicinal product in 150 ml of hot water as a compress or poultice, several times a day. - The preparation contains not less than 1.5% flavonoids, expressed as violanthin calculated relative to the dried plant.


Interactions

Médicaments

Antiplatelet agents/Anticoagulant: low interaction

Because of the presence of coumarins and salicylates, wild pansy should be used with caution in patients on anticoagulants, as it may have additive effects.


Precautions

Pregnant women: avoid

In the absence of sufficient data, use during pregnancy is not recommended.

Breastfeeding women: avoid

In the absence of sufficient data, use during breastfeeding is not recommended.


Contraindications

G6PD deficiency: contraindicated

There is a case report of hemolysis in an infant with G6PD deficiency who consumed boiled wild pansy extract. The methyl ester of salicylic acid, a constituent of wild pansy, is thought to have been responsible for this effect.

Allergies: contraindicated

Wild pansy is contraindicated in cases of a true allergy to salicylate derivatives.
