Fucus Vesiculosus

18/Description

About

Fucus vesiculosus is a type of brown seaweed. People use the whole plant to make medicine.

People use Fucus vesiculosus for conditions such as thyroid disorders, iodine deficiency, obesity, and many others, but there is no good scientific evidence to support these uses. Using Fucus vesiculosus can also be unsafe.

Don't confuse Fucus vesiculosus with bladderwort.

How it works

Fucus vesiculosus contains varying amounts of iodine. The iodine might help prevent or treat some thyroid disorders. Fucus vesiculosus also might have antidiabetic effects, and may affect hormone levels. But more information is needed.

Effectiveness

Not Proven
Obesity

Early research suggests that taking Fucus vesiculosus along with lecithin and vitamins doesn't help people lose weight.

Achy joints (rheumatism)
Arthritis
"Blood cleansing"
Constipation
Digestive problems
"Hardening of the arteries" (arteriosclerosis)
Iodine deficiency
Thyroid problems, including an over-sized thyroid gland (goiter)
Other conditions

Concerns

Possibly safe

Fucus vesiculosus is POSSIBLY SAFE when applied to the skin

Possibly unsafe

It is POSSIBLY UNSAFE when taken by mouth. It may contain high concentrations of iodine. Large amounts of iodine can cause or worsen some thyroid problems. It may also contain heavy metals, which can cause heavy metal poisoning. Treatment of thyroid problems should not be attempted without medical supervision.

18/Warnings

Warnings

Pregnancy and breast-feeding: Fucus vesiculosus isPOSSIBLY UNSAFEduringpregnancyandbreast-feeding. Don't use it.

Bleeding disorders: Fucus vesiculosus might slow blood clotting. In theory, Fucus vesiculosus might increase the risk of bruising or bleeding in people with bleeding disorders.

Diabetes: Fucus vesiculosus may affect blood sugar levels. If you have diabetes and take medications to lower your blood sugar, adding Fucus vesiculosus might make your blood sugar drop too low. Monitor your blood sugar carefully.

Infertility: Preliminary research suggests that taking Fucus vesiculosus might make it harder for women to get pregnant.

Iodine allergy: Fucus vesiculosus contains significant amounts of iodine, which could cause an allergic reaction in sensitive people. Don't use it.

Surgery: Fucus vesiculosus might slow blood clotting. There is a concern that it might cause extra bleeding during and after surgery. Stop taking Fucus vesiculosus at least 2 weeks before surgery.

Thyroid problems known as hyperthyroidism (too much thyroid hormone), or hypothyroidism (too little thyroid hormone): Fucus vesiculosus contains significant amounts of iodine, which might make hyperthyroidism and hypothyroidism worse. Don't use it.

Interactions

Always consult with your doctor.
Moderate
Lithium

Fucus vesiculosus can contain significant amounts of iodine. Iodine can affect the thyroid. Lithium can also affect the thyroid. Taking iodine along with lithium might increase the thyroid too much.

Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs)

Fucus vesiculosus can contain significant amounts of iodine. Iodine can affect the thyroid. Taking iodine along with medications for an overactive thyroid might decrease the thyroid too much, or may affect how antithyroid medications work. Do not take Fucus vesiculosus if you are taking medications for an overactive thyroid.Some of these medications include methenamine mandelate (Methimazole), methimazole (Tapazole), potassium iodide (Thyro-Block), and others.Fucus vesiculosus might slow blood clotting. Taking Fucus vesiculosus along with medications that also slow clotting might increase the chances of bruising and bleeding.Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.
