Radish oil is known to have many different health benefits, similar to those attributed to the radishes commonly eaten in salads. It is important to note, however, that this type of oil is extracted from radish seeds, not the roots. One of the best-known uses of oil is as a topical skin remedy, with examples of this use going back to ancient Rome. Many people believe that this substance can also be used for stomach illnesses, greasy skin, and the promotion of circulation. As with all herbal remedies, it is important to weigh the claims made by manufacturers against experience and scientific evidence.
One of the most well-attested benefits of radish oil is in the treatment of skin conditions. Ringworm, for example, is often treated with this oil, as are other topical fungal infections. Usually, the oil is used to directly treat cases of infection, not as a daily treatment. Even so, some people experience symptoms more frequently than others and may have success using the oil on a regular basis.
Internal uses of radish oil are also common, and this substance is thought to treat a wide variety of digestive problems. It is often reported that the oil stimulates the appetite, which is valuable after illnesses. Use as a laxative and diuretic have also been recommended by some sources, although the effects vary depending on the individual constitution. Most of the time, the benefits of the oil are thought to relate to current conditions, in that the oil restores balance to an unhealthy system.
There is some evidence that this type of oil may have respiratory and circulatory benefits as well. In cases of chest congestion, the oil may be used as an expectorant. This usually involves internal application of the oil. Improved circulation can also be achieved with the oil, although this use is rarer, as there are more effective herbal remedies available.
It is important to realize that not all of these benefits are consistently experienced across the population and that radish oil can actually be harmful for some people. The benefits it holds must be weighed against the risks of indigestion. Some people who suffer from conditions like ulcers may be at an increased risk for these side effects. Many of the benefits associated with the oil are also benefits of radish juice, so this can sometimes be used as an alternative. All of the benefits of radish oil are short-lived, and the oil should not be taken for more than four weeks.
