Uses & Effectiveness
Possibly Ineffective for
- Abortion. The effect of laminaria on the time need to induce an abortion is conflicting. Some research shows that laminaria can shorten delivery time. Other research shows no effect. Laminaria might also increase the chance of seizures due to fever when used for abortions.
- Preparation ("ripening") of the cervix in women, such as during childbirth or procedures. Although laminaria might speed up childbirth, it doesn't seem to reduce the number of women who need Cesarean sections to deliver. Laminaria also increases the chance of infection in both mother and infant.
Insufficient Evidence for
- Weight loss.
- High blood pressure.
- Cancer prevention.
- Heartburn.
- Other conditions.
Side Effects & Safety
Laminaria is LIKELY SAFE when it is consumed in amounts found in food. In some people it can cause acne or worsen thyroid diseases.Laminaria is POSSIBLY UNSAFE when taken by mouth as a medicine. It contains iodine in amounts that are high enough to harm the thyroid, the gland that uses iodine to make hormones. The average laminaria-based supplement might contain as much as 1000 mcg of iodine. Taking in more than 150 mcg of iodine per day can cause a normal thyroid to become overactive or underactive, or make an overactive thyroid worse. Some laminaria products also contain significant amounts of arsenic, a chemical element that is poisonous.
Special Precautions & Warnings:
Pregnancy and breast-feeding: The use of laminaria directly on the cervix during pregnancy or childbirth is POSSIBLY UNSAFE when used to ripen the cervix and LIKELY UNSAFE when used to induce labor. It can cause serious side effects for both mother and child, including infection, rupture of the cervix, and infant death. Taking laminaria by mouth during pregnancy is UNSAFE because laminaria can affect hormones.Taking laminaria by mouth during breast-feeding is LIKELY UNSAFE because laminaria might contain some poisonous chemicals.
If you are pregnant or breast-feeding, it’s best to avoid laminaria.
Kidney problems: Laminaria might cause dangerously high potassium and iodine levels. Don’t take laminaria if you have kidney problems.
Thyroid problems: Laminaria contains significant amounts of iodine, which might make thyroid problems worse. Don’t take laminaria if you have thyroid problems.
Interactions
Moderate Interaction
Be cautious with this combination
-
Digoxin (Lanoxin) interacts with LAMINARIA
Laminaria contains large amounts of potassium. Large amounts of potassium can increase the effects and side effects of digoxin (Lanoxin). Do not take laminaria if you are taking digoxin (Lanoxin).
-
Medications for high blood pressure (ACE inhibitors) interacts with LAMINARIA
Laminaria contains large amounts of potassium. Some medications for high blood pressure can increase potassium levels in the blood. Taking laminaria along with some medications for high blood pressure might cause too much potassium in the blood.<br/><br/> Some medications for high blood pressure include captopril (Capoten), enalapril (Vasotec), lisinopril (Prinivil, Zestril), ramipril (Altace), and others.
-
Potassium supplements interacts with LAMINARIA
Laminaria contains large amounts of potassium. Taking potassium supplements along with laminaria might cause too much potassium to be in the body. Do not take laminaria if you are taking potassium supplements.
-
Thyroid hormone interacts with LAMINARIA
The body naturally produces thyroid hormones. Laminaria might increase how much thyroid hormone the body produces. Taking laminaria along with thyroid hormone pills might increase the effects and side effects of thyroid hormones.
-
Water pills (Potassium-sparing diuretics) interacts with LAMINARIA
Laminaria contains large amounts of potassium. Some "water pills" can also increase potassium levels in the body. Taking some "water pills" along with laminaria might cause too much potassium to be in the body.<br/><br/> Some "water pills" that increase potassium in the body include amiloride (Midamor), spironolactone (Aldactone), triamterene (Dyrenium), and others.
Dosing
The appropriate dose of laminaria depends on several factors such as the user’s age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for laminaria. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
