What are the pharmacological activities of Viola mandshurica?
This plant has potent anti-inflammatory and anti-asthmatic pharmacological activities that make it valuable for treating respiratory conditions. The bioactive compounds found within its tissues work to reduce swelling and systemic inflammation in the body. These medicinal properties specifically help in relaxing the bronchial muscles to alleviate symptoms of asthma. Furthermore, its ability to suppress inflammatory mediators can mitigate the severity of various allergic reactions. Such biological actions suggest that Viola mandshurica holds significant potential for further pharmaceutical development.
According to a study published by "Journal of ethnopharmacology", Viola mandshurica ethanolic extract significantly inhibited increases in total immunoglobulin E (IgE) and cytokines IL-4 and IL-13 levels in serum and bronchoalveolar lavage fluid (BALF). In a mouse model where female BALB/c mice were sensitized on days 0 and 14 and given intranasal OVA on days 28-30, the extract was administered orally from days 28 to 30. The extract effectively suppressed airway hyperresponsiveness (AHR), eosinophilia, and mucus hypersecretion in mice with OVA-induced asthma. These results suggest that Viola mandshurica may be a valuable lead material for anti-asthma drug development.
The primary pharmacological activities of this plant are shown in the list below.
- anti-asthmatic
- anti-inflammatory
What medicinal compounds this plant contains?
This plant contains the medicinal compounds hesperetin, luteolin, tectoriidin, cyclotides, and resveratrol. These diverse phytochemicals contribute to the biological activities and potential therapeutic uses of the species. Research indicates that the presence of these specific flavonoids and polyphenols may offer antioxidant and anti-inflammatory benefits. Furthermore, the unique cyclotides found within the plant are of significant interest in pharmacological studies due to their structural stability. Together, these substances form a complex chemical profile that characterizes the medicinal properties of Viola mandshurica.
According to a study published by "Journal of microbiology and biotechnology", the chloroform extract of fermented Viola mandshurica contains main phenolic compounds identified as tectoriidin, luteolin, resveratrol, and hesperetin. This chloroform extract of fermented Viola mandshurica, referred to as CEFV, significantly inhibited NO production and reduced the expression of inducible nitric oxide synthase at both protein and mRNA levels. CEFV also decreased PGE2 production and suppressed COX-2 expression. Furthermore, the extract inhibited the activation of the ERK and JNK pathways in RAW264.7 cells. These actions allowed CEFV to suppress NF-κB activation, which acts as a key regulator in the inflammatory response.

What health conditions is this plant used for?
This plant is used for treating airway hyperresponsiveness, airway inflammation, allergic asthma, bronchial asthma, and mucus hypersecretion. Its medicinal properties help stabilize the respiratory passages to reduce sensitivity to various environmental triggers. By addressing underlying airway inflammation, it provides relief for those suffering from chronic bronchial asthma. The plant also plays a role in regulating mucus hypersecretion to clear the respiratory tract more effectively. These combined effects make it a valuable resource for managing the complexities of allergic asthma.
According to a study published by "Journal of ethnopharmacology", Viola mandshurica ethanolic extract was investigated for the treatment of bronchial asthma in an ovalbumin-induced asthma model using female BALB/c mice. The mice were sensitized with intraperitoneal ovalbumin on days 0 and 14, followed by intranasal administration on days 28-30. Treatment with the extract from days 28 to 30 significantly inhibited increases in total immunoglobulin E and cytokines IL-4 and IL-13 levels in serum and bronchoalveolar lavage fluid. Furthermore, the extract effectively suppressed airway hyperresponsiveness, eosinophilia, and mucus hypersecretion in these mice. These results suggest that Viola mandshurica could be a useful herbal medicine for asthma treatment and a valuable lead material for drug development.
The main health conditions this plant is used for are shown in the list below.

These different methods allow for the targeted delivery of its medicinal properties depending on the severity of the ailment. Each preparation type aims to utilize the plant's natural chemical constituents for therapeutic relief.
According to a study published by "Journal of microbiology and biotechnology", the chloroform extract of fermented Viola mandshurica (CEFV) was investigated for its effects on LPS-induced inflammatory response in RAW 264.7 macrophages. The CEFV significantly inhibited NO production and reduced the expression of inducible nitric oxide synthase (iNOS) at both protein and mRNA levels in a dose-dependent manner. Additionally, CEFV decreased PGE2 production, suppressed COX-2 expression, and inhibited the activation of the ERK and JNK pathways, though it did not inhibit the p38 pathway. This extract suppressed NF-κB activation and contained main phenolic compounds including tectoriidin, luteolin, resvera-trol, and hesperetin. Ultimately, CEFV exhibits potent anti-inflammatory effects by downregulating pro-inflammatory mediators in RAW 264.7 cells.
