Larch (Larix occidentalis)

Natural Anti-Metastatic and Immune Stimulant

Larch ArabinogalactansLarch is a deciduous conifer that contains an arabinogalactan similar to those found in other “immune-enhancing” herbs such as Echinacea, Baptisia and Turmeric.

Larch arabinogalactans have been shown to reduce the number of liver metastasis in multiple studies, perhaps by acting as a “reverse lectin” and blocking tumor binding sites. A similar effect has been noted for Modified Citrus Pectin. Larch also nourishes the gut flora and acts as a source of dietary fiber. A summary of the benefits of Larch are:

  • stimulates the immune system
  • helps prevent cancer metastasis
  • improves bowel flora (friendly gut bacteria)
  • acts as a source of dietary fiber

Larch and/or Modified Citrus Pectin should be considered by anyone with cancer to help prevent or delay metastasis.

Suggested Dose: two teaspoons, 2-3 times per day. This may be added to your Super Shake.
