Radish: Uses, Benefits, Side Effects and More!
Introduction:
The common radish is scientifically known as Raphanus sativus L. It belongs to the family Brassicaceae. It is considered a root vegetable as it can store starch and other bioactive compounds. The shape of radish resembles actual roots. Its colour varies from white in Asia to red and different colours (green, purple and black) in Europe, although its flesh is white in most Asian and European countries. The intense flavour and diverse tastes of radish are owing to an essential compound known as isothiocyanate. Due to this characteristic flavour and taste, it is popular in countries such as Hawaii, Japan and the Philippines.1

| Properties of radish |
Properties of Radish:
Bioactive compounds such as polyphenols, glucosinolates and isothiocyanates contribute to the beneficial potential of radish.1,3 It is also used as a remedy in Indian, Unani and Greeko-Arab to manage various conditions.4 The potential properties of radish are:
- May have blood pressure-lowering potential
- May be potentially Heart-protective
- May have anti-microbial (reduces the growth of micro-organisms) potential
- Mat be a potential anti-oxidant1
- May have anti-cancer (prevents the growth of cancer cells) potential
- May be potentially Liver-protective
- May have Anxiety-reducing potential.3
1. Potential uses of radish for diabetes
Many studies show that radish extract contains antioxidants such as polyphenols that enhance insulin secretion. Further, radish extract was observed to potentially inhibit enzymes (glucosidase) that converts starch into simple sugars. It may augment the defence mechanism with its antioxidant activity, may reduce lipid peroxidation and oxidative stress. This may indicate that it may be helpful in maintaining energy metabolism and glucose uptake and may reduce glucose absorption in the blood.4However, Before using radishes or any other herbal remedies for diabetes, have a consultation with your Ayurvedic doctor provider so that he can guide you with correct choices.

| Potential uses for liver |
2. Potential uses of radish for liver
Several studies have recorded the potential beneficial effects of radish extract for the liver. In a study, the bioactive compounds in radish root and sprouts were found to reduce the seriousness of fatty liver disease in animal models. In another study on animal models, black radish extracts exhibited liver protective effects. Further, the administration of a radish extract resulted in reduced oxidative stress and prevented fat accumulation. The effects shown by radish could be credited to the antioxidant activity of bioactive compounds present in radish extracts.
Therefore, it may help with the decrease in the levels of enzymes that indicate liver damage and the reduced levels of lipids and cholesterol suggest that radishes might indeed have potential benefits for liver. 3 Further studies are needed to establish benefits of radish for human liver. If you are suffering from any liver related issues, consult your doctor before using radish or any other herbal remedies.
3. Potential uses of radish for cancer
Due to presence of secondary metabolites such as glucosinolates, eating may have benefits that may help people with cancer. Detoxification enzymes, prevention of cell cycle progression, activation of apoptosis (cell death) are the potential anticancer mechanism may be exhibited by bioactive compounds present in radish as per studies. These are responsible for anticancer activity of radish against different types of cancer cell lines.3
Cancer is a severe medical condition which requires medical diagnosis and treatment. Before using any herb or fruit, consult your doctor.

| Potential uses for hairs |
4. Potential uses of radish for hair
In a study conducted on animal models, it has been shown that saponins extracted from radish may be helpful with the loss of human hair. The radish crude saponin-treated group demonstrated the potential benefits for hair follicles (HFs) in the deep part of the skin and may ultimately develop HFs corresponding to the anagen phase (or active phase) of the hair-growth cycle.5 The benefits of radish are not sufficiently studied for human hair. If you face hair fall, reach out to your healthcare provider for a consultation.
Though the studies above show the benefits of radish in various conditions, but these are insufficient and there is a need of further studies to establish the true extent of benefits of herb on human health.

| How to use radish |
How to Use Radish?
The edible part of radish is mainly its roots. Also, we can eat its leaves, pods, seeds, flowers and sprouts of radish in various forms.1,3 Radish can be used in the following ways:
- Roots of radish are eaten in salads or cooked with other vegetables.
- Roots of radish are also used in curries.
- Processed radish roots are consumed in Asia as dried roots or canned pickles.1,3
- You can also blend a bit of radish with other tastier vegetables in your smoothies for some colour and a hint of its distinct taste.
You must consult a qualified doctor before taking any herbal supplements. Do not discontinue or replace an ongoing treatment of modern medicine with an ayurvedic/herbal preparation without consulting a qualified doctor.
Side Effects of Radish:
In a study on animal models, it has been seen that feeding animals with high quantities of radish led to certain side effects on the thyroid glands and its functioning as described as follows:
- Reduced levels of thyroid hormone
- Increase in weight of thyroid gland
- Decrease in the activity of thyroid peroxidase
- Increase in thyrotropin level (a hormone secreted by the pituitary gland) similar to the condition in which the thyroid gland does not produce enough hormones even after administration of iodine.6
Therefore, we should take care while consuming radish in large quantities and it is better to enjoy it in moderate amounts.6 Moreover, if you observe discomfort or any other uncomfortable symptoms on eating radish, you must consult your Ayurvedic physician. They will be able to assess the situation and guide you regarding the course of action further. Even natural preparations can show specific side effects on individuals as everyone’s body reacts differently to certain compounds present in them.

| Precautions to take with radish |
Precautions to Take with Radish:
Radish is generally considered to be safe if it is taken in the recommended dosages and as food. However, general precautions should be followed while consuming radish. Please do not try to treat yourself by consuming herbs. Ayurvedic herbs may have potential benefits, but it is advisable to consult a qualified Ayurvedic physician before taking any herb for its health benefits.
Studies on animal models show that having too much radish can cause an increase in the level of thyrotropin. 6 However, no valid study provides evidence on safety precautions to be followed with radish extracts. However, extra care needs to be taken by pregnant women, lactating mothers, children, and older people while having radish. In case of any unusual symptoms, immediately consult your Ayurvedic physician.
Interactions With Other Drugs:
We cannot deny the possibility of certain drugs reacting with herbs and food like radish. Therefore, it is essential to consult your Ayurvedic physician before consuming any herbal item in more than regular quantities. Your Ayurvedic physician can appropriately modify the dosage and prescribe as per your current medications, conditions, and requirements.
