Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Dulse (Palmaria palmata) is a type of red seaweed traditionally consumed in various coastal regions, especially in Ireland, Scotland, and parts of Canada. Historically, it has been used as a dietary supplement to support thyroid health, including the management of goiter, a condition characterized by the enlargement of the thyroid gland. This traditional use is primarily due to dulse's naturally high iodine content, an essential trace element required for the synthesis of thyroid hormones. Goiter is often caused by iodine deficiency, and populations with low dietary iodine intake have historically turned to seaweeds like dulse as a natural source of this nutrient.

However, while the rationale for using dulse against goiter is clear from a nutritional perspective, there is limited direct scientific research specifically examining dulse's efficacy in treating or preventing goiter. Most evidence for its use is extrapolated from broader studies on iodine and thyroid health, rather than clinical trials involving dulse itself. Therefore, while the use of dulse for goiter has a strong traditional basis and is plausible due to its iodine content, scientific validation specific to dulse is lacking.

Caution is also advised, as excessive consumption of iodine-rich seaweeds can lead to thyroid dysfunction. In summary, the use of dulse for goiter is rooted in traditional practice and supported indirectly by nutritional science, but direct scientific evidence is limited.
