Douglas Iris

Meet the Douglas Iris (*Iris douglasiana*), a resilient and beautiful flowering plant native to the West Coast of North America. While often admired in gardens for its striking purple blooms, this botanical has a deep history in traditional wellness practices. Unlike common vitamins found in citrus, Douglas Iris is a specialized herbal ally. Traditionally used by indigenous peoples for digestive support and topical healing, modern supplement manufacturers often utilize its extracts to support the lymphatic system and reduce fluid retention. It acts as a gentle, natural ‘housekeeper’ for the body, helping to flush out excess water and toxins.

Health Benefits & Sources

Why You Need It

  • Reduces Water Retention: Acts as a mild diuretic, helping the kidneys flush excess fluids.
  • Supports Lymphatic Health: Traditionally used to encourage lymphatic drainage and reduce swelling.
  • Digestive Aid: Can help soothe an upset stomach and relieve mild bloating.
  • Topical Healing: Historically used as a poultice for skin irritations and wounds.

Deep Dive

The primary mechanism of Douglas Iris in dietary supplements focuses on its role as a lymphagogue—a substance that stimulates lymph flow. The lymphatic system is your body's drainage network; when it slows down, you may experience puffiness or fluid buildup. By encouraging this flow, Douglas Iris helps reduce that 'heavy' feeling.

Additionally, its root contains iridin, a compound that provides antioxidant support. When applied topically (in salves or washes), the astringent properties of the plant help tighten skin and promote faster healing of minor scrapes and insect bites.

Natural Food Sources

Unlike essential nutrients like Vitamin C or Magnesium, Douglas Iris is a botanical herb. It is not found in standard fruits or vegetables. It is harvested from the wild or cultivated specifically for herbal medicine.
