To use the sharing features on this page, please enable JavaScript.

Fucus vesiculosus is a type of brown seaweed that grows in the Baltic Sea, Atlantic Ocean, and North Pacific Ocean. The whole plant is used as medicine.

Fucus vesiculosus contains varying amounts of iodine. Iodine might help prevent or treat some thyroid disorders. Fucus vesiculosus also might have antidiabetic effects and affect hormone levels.

People use Fucus vesiculosus for thyroid disorders, obesity, aging skin, constipation, and many other conditions, but there is no good scientific evidence to support these uses.

Don’t confuse Fucus vesiculosus with algin, bladderwort, blue-green algae, ecklonia cava, or laminaria. These are not the same.

There is interest in using Fucus vesiculosus for a number of purposes, but there isn’t enough reliable information to say whether it might be helpful.

When taken by mouth: Fucus vesiculosus is possibly unsafe. It can contain high concentrations of iodine. Taking large amounts of iodine can cause or worsen some thyroid problems. It might also contain heavy metals, which can cause heavy metal poisoning.

When applied to the skin: Fucus vesiculosus is possibly safe.

Special precautions & warnings:

Pregnancy and breast-feeding: Fucus vesiculosus is possibly unsafe to use while pregnant or breast-feeding because it might contain iodine and heavy metals. Don’t use it.

Iodine allergy: Fucus vesiculosus may contain large amounts of iodine, which could cause an allergic reaction in sensitive people. Don’t use it.

Surgery: Fucus vesiculosus might slow blood clotting. It might cause extra bleeding during and after surgery. Stop taking Fucus vesiculosus at least 2 weeks before surgery.

Thyroid disorders: Fucus vesiculosus may contain large amounts of iodine. Long-term use or high doses of iodine might make certain thyroid disorders worse. Also, people with autoimmune thyroid disease might be especially sensitive to the harmful effects of iodine.

Moderate

Be cautious with this combination.

Lithium

Fucus vesiculosus can contain large amounts of iodine. Large amounts of iodine can change thyroid function. Lithium can also change thyroid function. Taking Fucus vesiculosus along with lithium might increase the risk of thyroid function changes.

Medications for an overactive thyroid (Antithyroid drugs)

Fucus vesiculosus can contain large amounts of iodine. Iodine can increase or decrease thyroid function. Taking Fucus vesiculosus along with medications for an overactive thyroid might change the effects of these medications.

Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs)

Fucus vesiculosus might slow blood clotting. Taking Fucus vesiculosus along with medications that also slow blood clotting might increase the risk of bruising and bleeding.

Minor

Be watchful with this combination.

Medications changed by the liver (Cytochrome P450 2C8 (CYP2C8) substrates)

Some medications are changed and broken down by the liver. Fucus vesiculosus might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.

Medications changed by the liver (Cytochrome P450 2C9 (CYP2C9) substrates)

Some medications are changed and broken down by the liver. Fucus vesiculosus might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.

Fucus

Back to list

Composition

It is believed that fucoidin in fucus is a reserve nutrient instead of laminarin, the content of which in this type of algae is very small. Fucoidin and other salts of fucoid acid form a group of fucoidants. It is to this group of substances that fucus owes much of its healing properties, such as immunomodulatory, anticoagulant, detoxifying, etc.

It is due to the gelling properties of alginic acid, which is a hydrophilic colloidal substance that can absorb water and swell approximately 25–35 times, that bladder fucus increases the volume of the stomach, promotes the gradual absorption of carbohydrates and fats into the blood, and thereby regulates appetite.

Properties

Fucus vesicles has anti-atherosclerotic, anti-inflammatory, antimicrobial, wound healing and endoecological effects on the body. It increases the activity of enzymes involved in the conversion of cholesterol into bile acids, prevents the deposition of cholesterol in the walls of blood vessels. At the same time, cholesterol biosynthesis is not disturbed, which eliminates the negative consequences of this process.

Fucus vesicularis effective in inflammatory diseases of the genitourinary system, with dysbacteriosis – inhibits the growth of pathogenic microflora. Algae components stimulate regenerative processes, promoting tissue granulation, epithelialization and scarring of wounds and ulcers. The combination of the antioxidant effect of the biologically active components of the algae with the enterosorption effect of alginic acid provides a radioprotective and detoxifying effect, including the removal of heavy metals from the body, including lead, mercury and radionuclides. Fucus vesiculosus also has an anticoagulant effect, contributes to the normalization of vascular permeability.

Application

In homeopathy, fucus is used to regulate the function of the thyroid gland, with inflammation of the lymph glands, hardening of the glands, cancerous lesions of the glands, skin, scrotum, lungs and others, with obesity.

Fucus is used for hypovitaminosis of various nature, to normalize the functions of the thyroid gland, to cleanse the body of salts of heavy metals, to normalize metabolism, to restore the normal activity of the gastrointestinal tract, to increase immunity, with cancer prevention, with allergic reactions of various origins, to restore after illness and antibiotic treatment, in diseases of the respiratory, nervous and circulatory systems, for the prevention of obesity. Fucus lowers cholesterol levels in the blood, strengthens the walls of blood vessels, and has high antibacterial and antiviral activity.

Included in the following preparations:

What is fucus? What are its miraculous properties?

Miraculous properties of fucus algae powder

Fucus is a very useful and quite demanded algae, which has not only a lot of useful properties, but also a pleasant and unusual taste.

This type of algae is very easy to distinguish from others: on its leaves there are small green bubbles, thanks to which the plant is upright under water.

Fucus grows almost anywhere on the planet, but its greatest accumulation is observed in the shallow waters of the Pacific and Atlantic oceans, in the northern and western parts of the Baltic Sea, in the Barents and White Seas.

Due to its unique properties, preparations from this algae are used in cosmetology, cooking, traditional and folk medicine.

What is the secret of fucus? Why is it so popular and useful?

The main unique property of fucus is that its composition of salts is maximally similar to the composition of human tissue fluid. In addition, the chemical composition of the plant contains alginic acid concentrate, fucoidan and iodine.

• Iodine increases efficiency and endurance, strengthens the nervous system, relieves unwanted weight, but most importantly, blocks the negative effects of the environment (including protecting and cleansing the body from radioactive contamination).
• Fucoidan made a real moral explosion and revolution in the pharmaceutical industry. Scientists have found that fucus, and in particular the powder from it, has powerful anti-inflammatory and anti-inflammatory properties. But most importantly, it has the ability to destroy low-quality oncological tumors. And this means that fucus powder is a promising tool for fighting cancer.

In addition, fucoidan, which is found in fucus powder, has a positive effect on blood composition, prevents the formation of thrombosis and prevents the development of diabetes, stabilizing blood sugar levels.

• Alginic acid absorbs water very well. It contains vitamins A, B, E, C, boron, sulfur, iron and about 25 more useful trace elements.

The composition and beneficial properties of fucus

Useful trace elements that are part of the fucus powder help fight not only the common cold, but also more problematic diseases, including tuberculosis and cancer. For example, half a teaspoon of seaweed powder is enough to meet the daily requirement of iodine for three adults.

The positive effect of the powder on the human body is a beneficial effect on the endocrine system, which in turn affects the smooth and normal functioning of the whole organism.

During the last century, scientists have carried out many experiments aimed at investigating the effect of iodine on the human body. As a result, they found that taking iodine-containing foods, including fucus powder, can quickly lose weight. The fact is that the iodine contained in the plant accelerates the process of burning calories. The remaining minerals improve the absorption of fats and carbohydrates, reduce the feeling of hunger due to the fact that they swell in the human stomach.

Medical use

Fucus powder is used for slow metabolic processes, lowering blood sugar levels, maintains a feeling of satiety, breaks down fat deposits in tissues, stabilizes the intake of carbohydrates and fats after meals, and normalizes bowel function. In addition, fucus powder is a powerful detoxifier (clears the body of toxins) and improves immunity.

Fucus powder is used to make medicines that fight against:

• Overweight and obese;
• Constipation and other disorders in the gastrointestinal tract;
• Iodine deficiency in the body;
• Allergies, etc.

Fucus preparations are used not only internally. Various ointments are prepared from the powder of this algae, which help to heal minor cuts, various skin diseases, and even smooth out deep facial wrinkles.

Contraindications and possible harm

Excessive consumption of fucus powder can cause “non-fatal”, but rather unpleasant problems to the human body. An excess of iodine in the body can cause poisoning or malfunction of the endocrine system. In order to avoid such problems, before starting to take fucus preparations, it is necessary to consult with your doctor, having previously passed the tests.

It is strictly not recommended to take fucus powder or its other medicinal variants for pregnant women, lactating women, people with thyroid or hormonal disorders. It is also forbidden to take fucus for patients who will have surgery in the near future.

Fucus preparations should not be taken for more than 14 days. After the next course of eating algae, you need to take a break of several weeks.

How to take fucus powder by mouth

Three teaspoons is the daily intake of dried fucus.

It is forbidden to take dietary supplements, vitamin complexes and algae powder at the same time, and the use of fucus is also contraindicated if a person has an excess of iodine in the body.

Let’s take a look at a few recommended ways to take herbal preparations from a dry powder.
