Healing Benefits:
  • Fennel bulb and seeds can both provide super health benefits, including helping to lower blood pressure, aiding digestion, improving skin health and boosting bone health, among others. The fennel bulb is exceptionally high in fibre and rich in potassium and vit C. Fennel seeds are rich in flavonoid antioxidants and many other micronutrients.
  • Turmeric – the fresh root or powder – is a spice used widely in Asian cooking. It contains curcumin, renowned in Ayurvedic and Chinese medicine for its healing properties over thousands of years. These include supporting cardiovascular health, fighting inflammation and diabetes 2, lowering cholesterol, reducing depression, relieving indigestion, reducing Alzheimer’s disease risk, among others.
