What is Bladderwrack?

Bladderwrack is a type of seaweed. People use the whole plant to make medicine.

Bladderwrack is used for many conditions, but, so far, there isn't enough scientific evidence to determine whether or not it is effective for any of them. It's also important to note that it's not safe to take bladderwrack by mouth.

Bladderwrack is used for thyroid disorders including underactive thyroid (myxedema), over-sized thyroid gland (goiter), and iodine deficiency. It is also used for obesity, arthritis, joint pain, "hardening of the arteries" (arteriosclerosis), digestive disorders, heartburn, "blood cleansing," constipation, bronchitis, emphysema, urinary tract disorders, and anxiety. Other uses include boosting the immune system and increasing energy.

Some people also apply bladderwrack to the skin for skin diseases, burns, aging skin, and insect bites.

Don't confuse bladderwrack with bladderwort.

Insufficient Evidence to Rate Effectiveness for...

  • Obesity. Early research suggests that bladderwrack, used along with lecithin and vitamins, doesn't help people lose weight and keep it off.
  • Thyroid problems, including an over-sized thyroid gland (goiter).
  • Iodine deficiency.
  • Arthritis.
  • Achy joints (rheumatism).
  • "Hardening of the arteries" (arteriosclerosis).
  • Digestive problems.
  • "Blood cleansing".
  • Constipation.
  • Other conditions.
More evidence is needed to rate bladderwrack for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
