Does Milk Thistle Make You Thirsty

Milk thistle (Silybum marianum) has been used since ancient times to treat various medical conditions. It is often used to treat liver diseases as this herb is shown to have benefits in protecting and regenerating the liver. Although many of the studies conducted on this herb is limited, there is a growing interest in the use of milk thistle for a variety of health conditions. There has been some debate as to whether or not taking milk thistle could make a person thirsty.

Most people would say that it doesn’t make you thirsty, especially if taken as a supplement. However, some studies have shown that milk thistle may have a mild diuretic effect, which would cause an increase in urine production and therefore result in an increased thirst. This is most likely to be the case in people with kidney or liver dysfunction.

Discussions among experts vary on this topic. Some experts say that the diuretic effect of milk thistle is mild to none. They also believe that milk thistle has more of a detoxifying effect on the body, which increases the production of urine and reduces toxins in the body. This could lead to an increase in thirst, as the body is releasing more fluids and toxins than it is taking in.

However, other experts assert that the diuretic effect of milk thistle is too mild for it to have any observable effect on thirst. They argue that drinking plenty of fluids with the supplement should be sufficient to reduce any increase in thirst, as long as the person is taking the supplement with meals and in moderation.

Overall, it appears that milk thistle may cause a mild increase in thirst, not in all people, but in certain situations. For those who are taking the supplement, it would be best to be aware of the possibility of increased thirst and take precautions by drinking plenty of fluids throughout the day.

How Milk Thistle Affects Liver Health

The most common use of milk thistle is for the treatment of liver conditions. Milk thistle is thought to protect the liver from toxins by increasing the production of antioxidants, such as glutathione, which helps to reduce the damage caused by free radicals. It is also thought to have anti-inflammatory properties, which can help reduce inflammation in the liver.

Studies have been conducted to determine if taking milk thistle could help improve the symptoms of hepatitis, cirrhosis, and other liver conditions. The results of some studies have suggested that taking milk thistle could help improve liver function, although the evidence is limited.

In addition, some studies have shown that taking milk thistle can help reduce levels of liver enzymes, which are used to measure damage to the liver. These studies suggest that taking milk thistle may help to improve liver health in those with certain liver conditions.

Although milk thistle has shown promise in treating certain liver conditions, it is important to remember that more research is needed to fully understand its effects on the liver. Therefore, it is recommended that those with liver conditions consult with their doctor before taking any form of milk thistle supplement.

How Milk Thistle Affects Cholesterol Levels

Several studies have suggested that taking milk thistle could help to reduce cholesterol levels. In one study, it was found that people who had taken a milk thistle supplement for four weeks had a significant reduction in their total cholesterol levels.

The positive effect on cholesterol is thought to be due to the herb’s potential to reduce inflammation in the body, which can help to reduce the amount of cholesterol being absorbed from the foods we eat.

It is important to note that taking milk thistle will not magically lower cholesterol levels on its own. It is just one tool used in the prevention and treatment of high cholesterol. Therefore, it is important to follow a healthy diet and lifestyle if you want to reduce your cholesterol levels.

Side Effects and Drug Interactions

As with any supplement, milk thistle can have some side effects if taken in excess. Common side effects may include nausea, headache, diarrhea, or abdominal pain. These side effects may be more severe in those with pre-existing conditions such as hepatitis or cirrhosis.

It is important to be aware of the potential for drug interactions when taking milk thistle. This herb may interact with certain medications, such as diuretics, blood thinners, or chemotherapy, so it is important to consult with your doctor before taking this supplement.

In addition, milk thistle is considered to be a stimulant and should be used cautiously in people with bleeding disorders, heart disease, or kidney disease. Always consult with your doctor before taking milk thistle if you have any pre-existing medical conditions.

Risks and Benefits of Taking Milk Thistle

Milk thistle has become increasingly popular as a supplement in recent years. It is thought to have protective and regenerative benefits for the liver and may have potential benefits for the treatment of certain conditions. However, it is important to be aware of the risks associated with taking milk thistle, as well as its potential drug interactions and side effects.

When considering taking milk thistle, it is important to weigh the potential benefits against the risks. If you do decide to take this supplement, it is important to consult with your doctor and get regular check-ups to ensure that the supplement is not having any harmful effects on your health.

Availability and Dosage

Milk thistle is available in many forms, including capsules, tablets, and powders. The most commonly used form of milk thistle is the extract, which can be taken in pill form. It is also possible to make a tea from the leaves or to buy the extract as a liquid.

The recommended dosage of milk thistle will vary based on age, weight, and the condition being treated. It is important to follow the instructions on the label, as taking too much can be harmful. It is also important to note that you should not take milk thistle for more than six weeks without consulting with your doctor.


In conclusion, it appears that taking milk thistle may cause a mild increase in thirst in some people. However, this is not the case for everyone, and the diuretic effect is thought to be mild. Milk thistle is most commonly used for the treatment of liver conditions and appears to have some potential benefits for improving liver health. However, it is important to be aware of the risks associated with taking this supplement, such as drug interactions and side effects, and to consult with your doctor before taking milk thistle.
