If you want to detox your body of impurities, drinking vegetable juice is an excellent way to start. You don’t necessarily need to be on a juicing fast where that is all you drink but adding more natural juices you make yourself with no sugar or additives can still help to cleanse your body, particularly your kidneys and liver. Here is more information about doing a juicing detox.
To start with, a juicing detox is one where you are making your own juice at home. There are some all-natural bottled juices that can be used for a detox if you are in a pinch, but it is typically better to make the juice yourself. That way, you save money and can control all of the ingredients in your juice. You want to use whole, fresh veggies as much as possible. You can save on buying your produce by finding it at health food stores and farmer’s markets. This also makes it easier to find locally-grown, organic produce instead of what you find in the regular supermarket.
You can also go one step further by adding herbs to your juicer. You can also just add in the herbs later on by putting them in your glass. Herbs are also frequently used with infused water because they add more flavor, as well as letting you get some of their nutrients. Some useful herbs for a juicing detox are rosemary, basil, oregano, and thyme. But you can add any herbs that you like. Try to also get the herbs fresh instead of in a container or jar. If you can grow your own herbs, even better!
While this is a personal decision, you need to keep in mind that a regular juicing detox is not necessarily a cleanse. A cleanse is typically something where you have only that type of juice for a number of days, with absolutely nothing else. However, a detox doesn’t have to be this strict. You can still clean the toxins from your different organs with fresh juice made from veggies, and herbs.
Finally, since you might be eating less of other foods (even if you are not strictly having only juice), you may be missing some critical nutrients during the detox. To ensure you are not suffering from malnutrition, take additional supplements like a multi-vitamin. Also, talk to your doctor about what supplements you might need.
You can add in a couple of drops of Stevia and juice a lemon to take away the green taste. It is not recommended to mix fruits and veggies in a juice but if you are juicing for children or do not have any blood sugar issues than you can add some fruits to the juice, such as a 1/2 apple, kiwi or other sweet fruit of your choice. 
Some people don’t like sweet, and I love to add ginger, garlic or turmeric to my juice to give it that savory taste. Be easy with the garlic, experiment with the flavors, start small, you can always add more!. You might even find that a nice garlic green juice just hits the spot. Follow what your body is telling you.
Picking one day a week of just drinking green juices and water and herbal teas gives your digestive system a nice rest. You can start the night before – say skip the meal and have a green juice in the evening around 7 p.m., then you have sleep and drink green juices the next day until 7 p.m. where you could have soup or a smoothie, that would be a full 24 hrs of juice fasting/detoxing. Think about it, if you make green juices one day a week, that’s 52 days of juicing after one year. That is almost 2 months worth of juice detoxing!
