Throughout old cultures, horseradish was famous for its medicinal purposes. Till today it is used as an ingredient in alternative medicine.

Health impacts

Health benefits

Inflammation 

Horseradish and radish extracts have anti-inflammatory effects that have a similar effect compared to NSAIDs, like aspirin or ibuprofen. (1) (2)

Antioxidant

Horseradish extract has antioxidant effects, they function in scavenging oxidants and superoxides. These oxidants and superoxides are causative agents of many diseases including cancer. (3)

On the other hand, radishes have high antioxidative properties. These are attributed to their bioactive elements that fight off oxidation generated by the disease. (4)

Cancer

Horseradish extract has antimutagenic effects meaning that whenever there is a mutation in the DNA that induces cancer, horseradish extract has proven to eliminate the oxidative agents that cause that mutation and have direct antimutagenic effects on the DNA. (5) 

On the other hand, radish, specifically radish leaves, have anti-tumor effects that induce apoptosis of cancer cells; (programmed cell death of cancer cells). (6)

Cardiovascular health

Radishes have positive effects on cardiovascular health. As previously mentioned they reduce oxidative stress and inflammation which prevents blood vessel damage. In addition, it reduces blood pressure since it has anti-hypertensive properties. (7)

On the other hand, horseradish has antioxidative and anti-inflammatory properties which also decrease risks of developing cardiovascular diseases.

Diabetes

Radish has an anti-diabetic effect, it firstly regulates the absorption of dietary glucose. In addition to this, it has regulatory effects of hormonal regulation of blood sugar balance.

Reflux

Radish has an alkaline pH which reduces reflux in people who suffer from acidic reflux and heartburns.

Downsides & Risks

Reflux

Although horseradish has an alkaline pH; if consumed in large amounts it would induce stomach irritation and reflux. If consumed in large amounts, it can also induce vomiting. It is important to consume it in moderate amounts.

Thyroid hormones

Long-term consumption of radish has a negative effect on the thyroid gland. It mimics the symptoms of iodine deficiency hypothyroidism, even though iodine levels are normal.

Urinary system

Long-term ingestion of horseradish extract has shown to cause lesions in the urinary bladder. (9)

Summary

In summary, horseradish is richer in sodium, calcium, magnesium, vitamin C, and folate. Although radishes are also a good source of vitamin C. Radishes are richer in water and have fewer calories. They have various beneficial effects on overall health.
