Origin & History
Sargassum is a genus of brown macroalgae found in tropical and subtropical oceans, particularly abundant in the Atlantic, Caribbean, and Indo-Pacific regions. Unlike most seaweeds, many species are pelagic, forming vast floating mats on the ocean surface. This genus is recognized for its unique bioactive compounds and traditional medicinal applications.
“Sargassum has a significant history in Traditional Chinese Medicine (TCM), where it is known as "Hai Zao" and used to soften masses, treat goiter, and reduce swelling. In coastal medicine, decoctions were traditionally used for thyroid imbalances, lymphatic swelling, and phlegm, while sea baths and compresses were applied for skin healing.”Traditional Medicine
