Product: Bladderwrack

Latin Name: Fucus vesiculosus

Description: This perennial seaweed is native to the north Atlantic and Western Mediterranean and grows along the coastline, and reaches up to 1 metre in length. It has ribbon like fronds that are pale yellow to olive-brown in colour. It ‘roots’ itself to rocks by means of suction pad like disks at its base. The fronds are fan shaped with many divisions and wavy edges to each division and the individual divisions contain small bladders of air, which help keep the bladderwrack buoyant.

Interesting Fact: Bladderwrack is one of the most common seaweeds (algaes) to be found on the shores of the British Isles? In Victorian times the herbs was discovered to contain large amounts of iodine which was a useful means of treating goitre which was a common disease of the time, goitre presents as the swelling of the thyroid gland due to iodine deficiency.
