The most important benefit of poppy seeds is the prevention of heart disease. The seeds contain essential fatty acids like linoleic acid, which is an omega-6 fatty acid required for heart health. Please note that excess omega-6 fatty acids can harm your health. Hence, balance is key.

Poppy seeds also contain calcium and magnesium that regulate brain activity and aid in the development of neurons. The seeds can also treat sleeplessness.
There are so many other benefits these seeds offer. But before we get there, we want you to take a glimpse into the history of poppy seeds.

What Are The Health Benefits Of Poppy Seeds?
Poppy seeds have a wide range of benefits – they act as a cure for sleeplessness and mouth ulcers and enhance digestion. The seeds even improve female fertility to a large extent and can also aid in cancer prevention.
1. Improve Female Fertility
Studies have shown that flushing the fallopian tubes with poppy seed oil can boost fertility. Researchers speculate that the oil can dissolve any debris or mucus in the tubes and increase the chances of fertility. The technique, also called hysterosalpingography, had 40 percent of infertile women in the test group achieve successful pregnancies. Not only that, 29 percent of the infertile women in the group, who had their fallopian tubes infused with poppy seed water, achieved successful pregnancies (1).
Poppy seeds can also enhance sexual health. They contain lignans, compounds known to boost libido and sexual desire.
2. Enhance Digestion
Poppy seeds are sources of insoluble fiber, which can aid digestion. It also increases the bulk of the stool and helps treat constipation (2).
But still, we need more research in this aspect.
3. Reduce Sleeplessness
As per a study, consuming a poppy seed drink decreased the levels of cortisol in the body. This led to a calming effect as the stress levels eventually went down. More interestingly, the circadian rhythms in the test subjects showed a marked improvement. Also, the individuals felt less fatigued.
Amongst poppy seeds, opium poppy is known to be particularly effective in inducing sleep (3). It works by binding to opioid receptors in the body, which mediate its psychoactive effects. But exercise caution while giving it to kids. Consult your doctor before doing so.
You can also take poppy seed tea as a sleep aid before you go to bed. Just make a paste of poppy seeds and mix it with warm milk. Take it before bedtime. One cup of poppy seed tea would do the trick.
4. Reduce Mouth Ulcers
Though there is limited research on this, anecdotal evidence suggests that poppy seeds can help cure mouth ulcers. Poppy seeds are known to have a cooling effect on the body, which plays a role in mouth ulcer treatment.
Simply mix some crushed dry coconut, powdered sugar candy, and ground poppy seeds. Shape it into a pellet and suck on this for instant relief from mouth ulcers.
5. Boost Energy
This property of the seeds can be attributed to their high content of complex carbohydrates – the macronutrientsi XNutrients needed by the body to meet its energy requirements, such as carbohydrates, fat, and proteins. your body needs for energy. The seeds also help absorb calcium, the disruption of which can lead to fatigue.
6. Improve Brain Health
The brain requires essential nutrients like calcium, iron, and copper – minerals that poppy seeds are rich in. These minerals aid in the regulation of neurotransmittersi XChemical messengers in the body that carry signals from one nerve cell to another nerve or muscle cell, or a gland. and enhance brain function.
Poppy seeds might also cut the risk of cognitive disorderi XA category of mental health disorders that affect learning, memory, perception, and problem solving. . However, further research is warranted in this aspect.
7. Strengthen Bones
Poppy seeds are rich in calcium and copper. While the former improves bone health, the latter strengthens the bones as well as the connective tissue. Another mineral the seeds are rich in is phosphorus, which, along with calcium, makes up part of the bone tissue. And the manganese in the seeds aids the production of collagen, a protein that protects your bones from severe damage.
8. Regulate Blood Pressure
Jesse Feder, Clinical Dietitian at the Memorial Regional Hospital, says, “Poppy seeds contain certain antioxidants as well as healthy fats that can help control high blood pressure. The antioxidants can help decrease inflammation and radical oxide damage throughout your arteries and heart, which can help decrease your blood pressure. Additionally, healthy fats can help lower your bad cholesterol levels and help reduce plaque buildup in your arteries. This too can help decrease your blood pressure back to healthy levels.”
In addition, the oleic acid in poppy seeds helps lower blood pressure levels.

The zinc in poppy seeds can contribute to a strengthened immune system. The seeds also enhance the production of immune cells in the body. And the iron in the seeds also helps in this aspect.
The zinc in the seeds also helps ward off lower respiratory ailments and is thus used in natural remedies.
10. Improve Heart Health
Poppy seeds are loaded with dietary fiber, which helps lower cholesterol levels and ultimately improves heart health. As per a study, the cholesterol content in a food item decreased with a higher amount of poppy seed oil (4). This simply proves that adding the oil to your diet can make it more heart-healthy.
We discussed earlier that poppy seeds contain omega-6 fatty acids and how they can be good for the heart. Additionally, as per a report by Tufts University, the seeds also contain omega-3 fatty acids – popular the world over for their healthful benefits. And one of them is protecting the heart from disease (5). Omega-3s cannot be made in the body, and hence, they must be obtained from external sources. One such great source is a serving of poppy seeds.
11. Aid In Diabetes Treatment
Given that poppy seeds are high in fiber, they could be a preferred addition to a diabetic diet. And the manganese in the seeds might also aid in diabetes treatment.
However, we more research in this aspect. Consult your doctor before you take poppy seeds for this purpose.
12. Promote Vision Health
Poppy seeds are a good source of zinc, and certain studies say the mineral can aid vision health and even prevent serious eye diseases like macular degenerationi XAn eye condition in which the inner layers of the macula (central section of retina) are damaged, resulting in blurred or reduced vision. (6). The antioxidants in poppy seeds can also benefit the eyes.

It can also stop cancer cell proliferation.
According to another Indian study, poppy seeds can increase the activity of a carcinogen-detoxifying enzyme called glutathione-S-transferase (GST) by as much as 78%. This activity of poppy seeds, as per the study, is high enough for the food to be considered potent for cancer treatment (8).
The tincture of the poppy plant is said to treat cancerous ulcers (9).
14. Help Treat Kidney Stones
Poppy seeds contain potassium, one mineral known to offer protection against and even treat kidney stones. However, according to a report by the University of Maryland Medical Center, individuals with hyperoxaluria (an excessive urinary excretion of oxalate that increases the risk of calcium oxalate kidney stones) need to limit the amount of poppy seeds in their diet – as the seeds are high in oxalic acid (10).
15. Enhance Thyroid Function
Zinc is one of the minerals the thyroid gland needs for optimal functioning. Poppy seeds can play a vital role in this aspect as they are rich in zinc.
Also, iodinated poppy seed oil has been used in numerous parts of the world to treat iodine deficiency – the cause of thyroid dysfunction (11).
16. Have Analgesic Effects
Since ancient times, the seeds have been used in herbal remedies as an analgesic (for pain management). Even poppy tea (prepared by mixing the seeds in hot water) can offer analgesic benefits as per a health report (12).
The analgesic effects of poppy seeds are especially potent in the opium variety according to a report by Purdue University (13).
Daniel, a YouTuber, discusses the intense euphoria and energy poppy seeds provided as well as the challenges he faced due to its addictive nature. He explains, “You know what, I’m saying anyways the euphoria was very intense and the poppy seeds also seemed to give me this energy.

Proper selection of food items is vital, especially in the present scenario when food adulteration is a common phenomenon.
