Herbalism and the Thyroid Intensive

with Matthew Wood and Phyllis D. Light

Herbalist with 75 Years of Joint Experience as Consulting Herbalists & Herbal Authors

In this intensive you'll learn:

At first, all that was known about the human thyroid was that it needed iodine and it was responsible for heat generation. We learn about this in Matt and Phyllis' class Iodine, Evolution, and the Thyroid.

Signs, Symptoms & Diagnostic Terms
In addition to iodine deficiency, various types of goiter, swelling, and small lumps can occur in the thyroid—as well as cancer. 

We will address the four major conditions of the thyroid that are usually contemplated:

  • hyperthyroidism
  • hypothyroidism
  • Hashimoto’s disease (which usually ends in hypothyroidism)
  • under-secretion of thyroid-stimulating hormone in the pituitary
  • Wilson's Thyroid Syndrome

These can have a multitude of causes and whether we know the cause or not, there are effective remedies for all of these conditions.

Effective, Time-tested Remedies Matt and Phyllis have often and successfully used to improve thyroid conditions:

  • Lemon Balm
  • Motherwort
  • Lycopus
  • Poplar bark
  • Black Walnut
  • Ashwagandha
  • Iris
  • Poke Root

Also, learn what they've found to aid symptoms of Hashimoto's and regulate the pituitary function.

Causes of thyroid-related conditions, even unsuspecting ones like...

  • Misuse of the voice box and tensions in the upper chest, neck, and shoulder structures is known to cause hypothyroid.
  • Leaky gut is another little-known cause of thyroid conditions.
  • Thyroid imbalances are easy to correct.

like the class on iodine, i learned more about my own thyroid condition in these couple of hours than i have in years of inquiry. many sincere thanks to phyllis and matt for so much useful, accessible, and interesting information! i think the best part is that i feel more in control now of the outcome and expectations regarding my thyroid condition. the western docs immediately wanted to cut the whole thyroid out because of one smallish nodule! with the understanding i learned here i can put all the drama that that recommendation generated to rest and just concentrate on diet and herbs with confidence. invaluable. thank you both again.
