According to Bruce Fife, author of The Detox Book: How to Detoxify Your Body to Improve Your Health, Stop Disease and Reverse Aging, drinking Epson salt also helps to detoxify the liver.

A high intake of Epsom salt is dangerous and it is highly recommended to refer to the directions on the package before consumption. The recommended intake of Epsom salt is the amount mentioned on the package, which counts as one dose. It must be mixed with eight ounces of water, and few drops of lemon juice for taste.

Drinking Epsom salt may interact with medications such as antibiotics, and so it is advised to stop taking any medication or supplements two days prior to consumption. Epsom salt benefits include flushing out toxins, cleansing the liver, improving blood sugar levels, preventing blood clots, and many others.

  • Severe stomach pain
  • Vomiting
  • Nausea
  • Perforated bowel
  • Severe constipation
  • Bowel obstruction
  • Colitis
  • Irregular heartbeat
  • Toxic megacolon
  • Sudden change in bowel habits lasting two weeks or longer

People with sulfur allergies should not consume or apply Epsom salt, as they may experience skin irritation or itchiness. Frequent Epsom salt baths for more than 30 minutes can rob the body of moisture, causing dehydration, and at times, diarrhea. So, don’t overdo it.

For those taking cardiac medications or ciprofloxacin, it is highly recommended to avoid Epsom salt, as it may interact with these medications. After drinking Epsom salt, if you do not have bowel movements or if you experience rectal bleeding, consult your doctor immediately. These symptoms might lead to more serious conditions.

People suffering from heart or kidney problems should not drink Epsom salt, as there is a possibility of electrolyte imbalances and toxicity from magnesium or phosphorus. Older people have higher chances of gastrointestinal side effects and magnesium toxicity. If you are suffering from diabetes, kidney disease, or eating disorders, it is recommended to consult your doctor before drinking an Epsom salt solution.

Epsom salt must not be consumed during pregnancy, and especially if you are expecting to deliver the baby within two hours. It is considered a pregnancy category D drug that can harm the unborn baby. Prior to drinking Epsom salt, tell the doctor if you are pregnant, or planning to be pregnant. If consumed for more than five to seven days during pregnancy, Epsom salt can cause low levels of calcium and bone problems in an unborn baby.

Communicate with your doctor if you have taken magnesium sulfate prior to any surgery, even in the case of dental procedures.

Other Benefits of Epsom Salt

In addition to drinking Epsom salt as a laxative, other benefits of Epsom salt include using it as bath soak, foot soak, to draw out splinters, relieve sore muscles, and to ease the pain of sprains and bruises. However, these require more research and lack sufficient evidence. On the whole, Epsom salt seems to be beneficial not only for health, but also in beauty and skincare as well as cleaning stains on floors and walls.

By and large, Epsom salt can be used either topically or to drink. However, be sure to keep a time frame to do that, and do it in consultation with your doctor. Do not use it in excess quantities, and do not take Epsom salt baths for more than 30 minutes.
