Who should not take Flax Seed for migraines
Unripened Flax Seed pods are believed to be poisonous and shouldn’t be eaten. Raw Flax Seed or Flax Seed plant can increase levels of the dangerous chemical cyanide in the blood – this hasn’t been observed when supplements are taken at recommended doses.
Flax Seed or Flax Seed Oil should not be put on broken skin or open wounds and should be avoided by people with high triglycerides.
Flax Seed should not be used by people who suffer from diarrhea, irritable bowel syndrome, diverticulitis or inflammatory bowel disease because of it works as a laxative. People with diabetes should discuss it with their doctor before taking Flax Seed because it may increase blood sugar levels.
Flax Seed and Flax Seed oil may cause diarrhea. And because it contains a lot of fiber, Flax Seed must be taken with a lot of water, or it may worsen constipation or in severe cases cause intestinal blockage.
Flax Seed’s fiber may reduce the body’s ability to absorb oral medications. Therefore, it should not be taken within two hours of any other medications taken by mouth or with any other supplements.
Women who are pregnant, may become pregnant or who are breastfeeding should not take Flax Seed. Because it can have effects similar to estrogen, some doctors believe it can be dangerous to the pregnancy.
Use caution if you have a hormone-sensitive cancer and check with your doctor before using Flax Seed.
As with many herbal supplements and natural migraine remedies, Flax Seed hasn’t been studied enough in children and therefore shouldn’t be given to children.
