Knotweed (Fallopia japonica), often dismissed as an invasive weed, is a hardy plant native to Asia, now found worldwide, and surprisingly rich in nutrients and health-boosting compounds.
One of its standout components is resveratrol, known for its powerful antioxidant and anti-inflammatory properties.
Traditionally used in medicine, knotweed has recently gained attention for its potential to improve heart health, reduce inflammation, and support overall wellness.
#1. Boosts Heart Health
Knotweed is an excellent source of resveratrol, a compound that helps reduce bad cholesterol (LDL) levels and supports healthy blood pressure, improving blood flow.
Moreover, studies published in Nature Reviews Cardiology highlight its role in preventing arterial plaque buildup and reducing the risk of heart disease.
Adding knotweed supplements or teas to your routine can be a heart-friendly decision.
#2. Supports Joint Health
Rich in anti-inflammatory compounds, knotweed can alleviate joint pain and stiffness. These properties make it a valuable natural remedy for conditions like arthritis.
A Journal of Natural Products study confirmed that knotweed extract helps reduce inflammatory markers, easing discomfort in affected areas.
You can include knotweed in your diet to relieve chronic inflammation.
#3. Strengthens Immune System
Knotweed contains vitamins A and C, which are vital for immune support. Vitamin C, found at approximately 20 mg per 100 grams in young shoots, helps the body fight infections and recover faster.
Additionally, the plant’s antioxidant content protects cells from damage caused by free radicals. You can drink knotweed tea during flu season for a natural immunity boost.
#4. Enhances Skin Health
Antioxidants in knotweed, particularly resveratrol and flavonoids, work wonders for your skin. These compounds fight oxidative stress, contributing to premature aging and skin damage.
Furthermore, knotweed’s anti-inflammatory properties may help soothe redness and irritation. You can include it in skincare routines or consume it to support a radiant, youthful complexion.
#5. Aids Digestive Health
Knotweed’s natural compounds, including tannins, act as mild astringents, which help soothe upset stomachs and improve gut health.
The fiber content in knotweed also promotes regular bowel movements and prevents digestive discomfort.
You should try knotweed tea for a gentle way to ease indigestion and maintain a healthy digestive system.
#6. Supports Cognitive Function
The resveratrol in knotweed enhances blood flow to the brain, improving memory and focus.
Therefore, it is a great addition to the diets of older adults or anyone seeking to maintain mental clarity.
Research in Frontiers in Aging Neuroscience suggests that resveratrol may also lower the risk of neurodegenerative diseases like Alzheimer’s.Â
#7. Promotes Detoxification
Knotweed has mild diuretic properties that help the body flush out toxins. This supports liver and kidney function, ensuring these vital organs work efficiently.
Moreover, its antioxidant compounds protect against oxidative stress, which can damage organs over time. You can include knotweed in your detox regime for a natural cleansing effect.
#8. Relieves Tinnitus Symptoms
Knotweed’s resveratrol content may help reduce tinnitus symptoms, a condition characterized by ringing in the ears. Resveratrol improves blood flow to the inner ear, which can alleviate discomfort.
Although more human research is needed, studies in Hearing Research highlight the potential of plant-based compounds like resveratrol in managing auditory health.
How to Use Knotweed
- Herbal tea: Steep dried knotweed roots in hot water for a soothing tea.
- Supplements: Look for resveratrol-rich knotweed capsules for convenient use.
- Stir-fries: Add young shoots to vegetable stir-fries for a crunchy, nutritious meal.

Cautions and Precautions
Knotweed contains oxalates, which may increase the risk of kidney stones in susceptible individuals. However, cooking the plant can reduce its oxalate content.
In addition, there is limited research on its safety during pregnancy or breastfeeding, so you should consult your doctor before adding it to your diet.
Moreover, its resveratrol content may interact with blood-thinning medications, requiring caution for those on such treatments.
