Top 13 Side Effects Of Cilantro:

Here are the top 13 cilantro side effects

1. Liver Damage

Overconsumption of cilantro can take a toll on the liver and affect its activities badly (1). It contains certain volatile essential oils that trigger the functionality of the most significant organ of our body. It also contains a number of powerful antioxidants, which help in eliminating liver problems. But when you consume more than the recommended amount of the herb, you force these constituents to work in the reverse order, increasing bile secretion and ultimately harming the liver. There is more research needed to properly understand the relation between cilantro and liver damage.

2. Low Blood Pressure

Excess ingestion of cilantro is bad for your cardiac health, this is one of the adverse reactions to cilantro as it may make your blood pressure plummet too low (2). Anecdotal evidence suggests that you may experience mild euphoria by including lots of this herb in your daily diet. Apart from the fall in blood pressure, it might also cause light-headedness followed by unconsciousness.

3. Upsets Stomach

Cilantro is known to heal several gastrointestinal issues. But when you take cilantro overdose, you might end up upsetting your stomach and developing various digestive disorders. According to a medical report, consumption of 200 ml cilantro extract (10%) for one long week can result in cilantro-induced gastrointestinal symptoms like extreme gas formation, stomach pain, abdominal cramps, vomiting and sometimes even loose motion (3).

4. Diarrhea

In severe cases of upset stomach, you may develop mild to moderate diarrhea (3). It has also been reported that this condition can get worse leading to dehydration. Try to keep the quantity of cilantro under control while incorporating it in your regular meal.

5. Breathing Problems

If you already suffer from some respiratory issues, it is advised not to consume excessive cilantro (4) It can give you acute breathing problems that can eventually lead to chronic lung diseases like cilantro-induced asthma. Sometimes the shortness of breath caused by too much cilantro intake can also come with a dry and tight throat.

6. Chest Pain

Though a little uncommon, some may experience chest pain after eating excessive amounts of cilantro. Anecdotal evidence suggests that it not only causes extreme discomfort but can also become chronic over time. Therefore, make sure that you consult your doctor before increasing the quantity of the herb in your daily diet.

7. Skin Sensitivity

Photosensitivity is one of the reactions of cilantro allergy (3). The green leafy herb contains certain acidic elements like psoralen, which can make your skin highly sensitive to sunlight (5) (6). In such situations, whenever your skin is exposed to the sunlight as well as ultraviolet rays, you get sunburns. It may also make you prone to skin cancer. Therefore, it is better to stay away from the scorching sunlight or use a good sunblock cream regularly.

Cilantro is the Spanish name for coriander. The leaves are popularly known as cilantro in the West, while the seeds are called coriander seeds.

8. Allergic Reactions

The protein content of cilantro is misinterpreted as ‘detrimental’ by our body and an antibody named IgE is automatically formed within our system to ‘counterbalance’ their negative effects. Cilantro allergies leave you with itching, swelling, irritation, rash, hives, etc., upon overconsumption or direct contact with it (7). The most severe allergic reactions that you may have to experience are eczema patches, dermatitis, and cilantro-induced anaphylaxis(8). You may also notice cilantro-induced urticaria or dermatitis.

9. Inflammation

Another common side effect of cilantro intolerance is oral inflammation (7). Usually, the lips, gums, and throat are inflamed in this condition, and you might experience cilantro-induced angioedema (swelling of deeper layers of skin, often around the eyes) (9). However, your face may also get flushed while giving you a tingling sensation.

10. Fetal Damage

When it comes to cilantro and pregnancy, there are some things you need to know. Eating lots of cilantro during pregnancy can be dangerous for the health of your fetus or baby. Some components of the herb are known to hamper the normal activities of the female reproductive gland, which can either cause harm to the expectant mothers or damage the overall health of the developing fetus. However, there is no scientific evidence to back this risk.

11. Kidney Stones

Cilantro contains saponins (10). When you consume this herb, your body breaks down the saponins into smaller compounds that are easier to excrete from your system. However, if you do not drink enough water while consuming cilantro, the amount of saponin that is being broken down could increase and lead to the formation of kidney stones.

12. Kidney Damage

Did you know there is a connection between cilantro and kidney damage? Cilantro contains insoluble oxalates, which are a form of oxalic acid (11). Oxalic acid is a natural substance found in many foods, but it is especially prevalent in spinach, rhubarb, and lima beans. Consuming too much cilantro can cause cilantro toxicity that may result in severe health problems, including kidney damage (12).

13. Issues With High Sodium

Cilantro is high in sodium content. One cup (100g) of cilantro contains about 46 mg of sodium (13). Therefore, excess consumption might not be good for your health. If you are trying to cut back on salt consumption, avoid adding cilantro to your diet.

Additionally, some individuals may not prefer cilantro’s soapy taste. Andrew Barney, a blogger, spoke about his dislike for cilantro. He said “My tongue proceeds to feel numb most of the time, and even if not, the taste stays in my mouth for hours. Making it almost impossible to eat something else instead. It really ruins the whole mood, and usually the day (i).”

The potential side effects of cilantro, such as allergic reactions, digestive issues, and others, are largely based on anecdotal evidence and some scientific studies. These effects may or may not apply to you, as individuals can react differently to foods and herbs. While cilantro is generally considered safe for most people when consumed in moderation, it is important to remain cautious. Understanding the potential side effects cilantro has on your health can help in making informed dietary choices
