Ashwagandha is considered to be one of the most powerful herbal supplements available and it is believed to have multiple health benefits.
However, as with all medicines whether herbal or prescription, there can be some side effects from taking Ashwagandha.
Possible Side Effects Of Ashwagandha
For the most part, it’s safe to use Ashwagandha for up to three months continuously as long as you aren’t taking too much. Anywhere between 300mg - 1500mg per day is acceptable, depending on how your body has adapted to it.
The issues start when you exceed this recommended dosage. If you do, especially when you first start taking Ashwagandha, you may suffer from any of the side effects listed below:
Vomiting & Diarrhea
Taking too much Ashwagandha can cause diarrhea or vomiting as your body tries to process the influx of vitamins compounds and minerals you’ve fed it.
These effects can also occur if you take Ashwagandha over a long period of time. This is why it’s recommended that you take a four-week break around every 3 months.
Drowsiness
Ashwagandha is believed to lower our cortisol levels and help us feel calmer. However, for this reason, taking too much can lead to drowsiness. You should also avoid taking Ashwagandha alongside any other sedatives.
Low Blood Pressure
Some people take Ashwagandha for this purpose. However, if you take too much and you don’t have any high blood pressure issues, you could lower your blood pressure to a dangerous level.
For this reason, you should also avoid taking Ashwagandha if you have been prescribed blood pressure medication.
Lower Blood Sugar Levels
Some studies suggest that ashwagandha may lower blood sugar by reducing inflammatory markers and improving insulin sensitivity. Insulin resistance is a condition in which the body's cells do not respond properly to the hormone insulin, which can lead to high blood sugar. Ashwagandha may also lower blood sugar by inhibiting the production of TNF-alpha and IL-6 which are cytokines that can impair insulin sensitivity. That is why, if you have diabetest or are on medications for it, always consult a healthcare professional before using ashwagandha as a supplement.
Liver Issues
Ashwagandha is generally safe for short-term use, but there have been rare reports of liver problems. While clinical trials haven't shown liver issues, some case studies link ashwagandha to mild-moderate liver injury. These cases typically resolved after stopping the supplement. It's important to consult a doctor before taking ashwagandha, especially if you have any pre-existing liver conditions.
Weight Loss
Some reports suggest that the use of ashwagandha root extract may cause some weight loss by reducing cravings and improving eating behaviours, which can be caused by chronic stress. Chronic stress itself can lead to weight gain, so ashwagandha may indirectly affect weight by reducing stress and anxiety. However, more studies are needed to confirm these findings.

Can Ashwagandha Be Bad For You?
While Ashwagandha is believed to possess some amazing health benefits, there are certain circumstances in which it can be considered bad for you. However, these usually only involve pre-existing conditions.
Below, we’ve put together some examples of situations where taking Ashwagandha could be bad for you.
Pregnancy
There is evidence to suggest that taking Ashwagandha during pregnancy could lead to miscarriage, so it’s advised that you stop taking it if you are pregnant.
The reason for this is that it can help strengthen the adrenal glands, reduce cortisol, and increase blood flow during menstruation. So, while it may be a helpful supplement for achieving conception, it shouldn’t be taken when you are pregnant.
Breastfeeding
If you are breastfeeding your child, it’s also recommended that you refrain from taking Ashwagandha.
While there isn’t any evidence to suggest it has a negative effect on your baby’s health, it’s still a powerful medicinal herb that your baby’s tiny body may not be able to process while it’s developing.
Surgery
If you are due to go into surgery, it’s recommended that you stop taking Ashwagandha at least two weeks beforehand. The reason for this is because Ashwagandha is believed to slow down your central nervous system, which is responsible for your body’s respiratory functions.
When you undergo anesthesia, the central nervous system is also slowed down, and if it’s slowed too much by a mixture of Ashwagandha and anesthesia, you could face difficulties breathing during and after surgery.
Possible Ashwagandha Interactions
Generally speaking, Ashwagandha is a wonderful medicinal herb that is believed to possess multiple health benefits. However, as with all herbal and prescription medications, there are some circumstances in which it may do more harm than good.
The most common of these circumstances is mixing Ashwagandha with another medicine. Certain prescription drugs may either enhance or negate the effects.
So, if you’re taking any of the drugs listed below, it’s a good idea to stop taking Ashwagandha until you’ve completed your prescribed course of treatment.
- Sedatives: Mixing sedatives with Ashwagandha can be harmful in two different ways. First of all, it can enhance the sedative effects, making you incredibly drowsy. Secondly, it can negate the effects of the sedative by raising your energy levels.
- Immunosuppressants: Since Ashwagandha is an adaptogen, it may reduce the effects of immunosuppressants. This is one of the reasons why it shouldn’t be taken by anybody with an autoimmune disorder.
- Antihypertensive drugs: Ashwagandha is also believed to lower blood pressure. This means it may interact negatively with any antihypertensive drugs and reduce your blood pressure too much.

Aside from the above medicines, another reason why somebody may find they have a bad reaction to Ashwagandha is that they are taking too much. As a rule, you should only be taking between 300mg - 1500mg per day and you should take a 4-week break every three months.
Who Should Not Take Ashwagandha?
Ashwagandha can be used by most people and it is a fantastic herbal supplement with lots of health benefits. However, there are some people that should avoid using Ashwagandha altogether.
This includes the following:
- Diabetics: This is a bit of a double-edged sword. As discussed, studies have shown that Ashwagandha can lower blood sugar levels. However, while this may make it sound helpful for diabetics, it can interfere with diabetes medication and cause your blood sugar levels to drop suddenly.
- Anybody suffering from a stomach ulcer: One of the potential side effects of Ashwagandha is vomiting and nausea. For this reason, it’s not advised to take it if you suffer from a stomach ulcer as it may irritate the GI tract.
- Pregnant women: You should stop using Ashwagandha straight away if you are pregnant. The main reason for this is because it can help stimulate the adrenal glands and maintain a healthy menstruation cycle. This isn’t something you want to happen when you’re pregnant.
- Anybody with an autoimmune disease: Whether you're suffering from rheumatoid arthritis, lupus, multiple sclerosis, or any other kind of autoimmune disease, you should not use Ashwagandha. The reason for this is because it increases activity in the immune system. As such, the symptoms of your autoimmune disease could get worse and any medications you’ve been prescribed could stop working.
- Hemophiliacs: Ashwagandha is also believed to have anticoagulant properties. For this reason, it shouldn’t be taken by anybody suffering from hemophilia or any other type of bleeding disorder. It may also negate the effects of certain blood disorder medications.
