Bladderwrack has proved most useful in the treatment of underactive thyroid glands and goiter. Through the regulation of thyroid function there is an improvement in all the associated symptoms. Where obesity is associated with thyroid trouble, this herb may be very helpful in reducing the excess weight. It has a reputation in helping the relief of rheumatism and rheumatoid arthritis, both used internally and as an external application upon inflamed joints.
Kloss, author of “Back to Eden” describe the medicinal properties of bladderwrack thus:
“The best remedy for obesity. Good for all glandular afflictions, goiter, and scrofula. Has an excellent effect on the kidneys.”
A seaweed common in colder waters.
The herb may be taken in tablet form as a dietary supplement or as an infusion by pouring a cup of boiling water onto 2-3 teaspoonfuls of the dried herb and leaving it to steep for 10 minutes. This should be drunk three times a day.
