According to Life and Health, nettle is a natural medicinal herb with the potential to help reduce symptoms of allergic rhinitis.
Scientists believe that the mechanism of action of nettle is related to the ability to regulate immune responses. Active substances in plants can help reduce the body's excessive reaction to allergens such as pollen and dust - common causes of allergic rhinitis.
Not only stopping at reducing symptoms, centipede also contributes to stabilizing the activity of immune cells, limiting the release of inflammatory mediators such as histamine - the main factor causing allergic manifestations.
Notably, nettle contains quercetin - a substance with strong antioxidant and anti-inflammatory properties. This active ingredient helps stabilize mast cell membranes, thereby reducing histamine release and supporting the balance of immune response.
Some clinical trials have recorded that users of tầm ma extract have a significant reduction in inflammatory reactions in the nasal mucosa. As a result, symptoms are improved with fewer side effects commonly seen in older generation antihistamines, including:
- Dry mouth: condition of reduced saliva secretion, causing a feeling of dryness and burning in the oral cavity.
- Sleepiness, reduced alertness: Affects concentration and living ability
For safe use, patients should not use fresh nettle leaves directly but should choose dosage forms such as dried winter leaf extract capsules or nettle tea.
The recommended dose is usually about 300mg per dose, divided into 2 times a day for capsules.
Maintaining use in combination with a healthy lifestyle can help better control allergic symptoms, while supplementing beneficial micronutrients for the body.
However, if you are pregnant or undergoing diabetes or high blood pressure treatment, consult your doctor before use to ensure there are no unwanted reactions.
