Side Effects of Nigella Sativa You Should be Aware of

Does Nigella Sativa have side effects?  As with all medicines and herbs, yes they can
have side effects if abused.  Nigella sativa can be toxic if taken in excess.  Never take more than 25 grams a day.

What is a safe dosage?  There is no cut and dry dosage for all disease.  There are around 40 dosages for different diseases and ailments.  Read the Dosage chart here.

So what is safe to take on a daily routine?  Never take more than 1 tablespoon of the oil or 7.5 teaspoons of the seeds or powder.  Even with cancer you do not need more than 1 tablespoon of oil daily.  Anyone or any blog that tells you elsewise should be avoided.

The percent of side effects with Nigella Sativa is so minute, it is almost not worth talking about, but there may be some who have slight reactions.

According to Web MD:

Black seed, when taken by mouth in small quantities, such as a flavoring for foods, is LIKELY SAFE for most people. Black seed oil and black seed extract are POSSIBLY SAFE when medical amounts are used short-term. 

Pregnancy and breast-feeding:  Never give Black seed to those who are pregnant or breast feeding. It is ok to give in small amounts in the food.   Black seed can slow down or stop the uterus from contracting.

Children: Black seed oil is POSSIBLY SAFE for children when taken by mouth short-term and in recommended amounts.  Children should be given 1/2 dose.  Never give children black seeds or oils under the age of 2 years old.

Bleeding disorders: Black seed might slow blood clotting and increase the risk of bleeding. In theory, black seed might make bleeding disorders worse.

Surgery: Black seed might slow blood clotting, reduce blood sugar, and increase sleepiness in some people.  Stop using black seed at least two weeks before a scheduled surgery.
According to Sloan Kettering Cancer Center, the Nigella Sativa is proven successful in the treatment of pancreatic cancer and shown to have a cure rate of 80% or more.  Nigella Sativa was also shown successful with high blood pressure, respiratory disease, inflammation and cell damage.

Noted Side Effects in Some Patients:

Contact Dermatitis

Contact dermatitis may occur when the oil is applied directly to the skin.  Keep in mind this is a tiny minute  of cases.   But the warning should be given.  It is best to test the skin first.  Always keep in mind to buy the best Nigella Sativa and not a cheap brand at a local India Shop.  The best black seed oil can be purchased here

How I suggest using the oil is heated in a stainless steel spoon.  Place a small amount in the spoon and hold over the fire for a few seconds until the oil is slightly warm and then apply to the areas of need.  If you have any reaction at all, you can mix the oil with an organic coconut oil.

Kidney or Liver Damage

The Nigella sativa seeds and oil  may cause kidney or liver damage when used in high doses. This is why I say never to take more than 1 tablespoon per day.  If you experience symptoms of kidney or liver damage, such as back or abdominal pain, urination changes, jaundice, fatigue or itchy skin, seek prompt care from your medical provider.

Interaction with Medications

Always talk with your doctor about any medication you are currently taking before you begin treatment with Nigella sativa. This supplement is an antioxidant and may protect cells against damage. Research has shown in the past that Nigella Sativa was taken satisfactorily with chemotherapy and radiology, but all cases are different and the buyer beware.

If you have hypertension, make sure to take the correct dosage (2 teaspoons per day) as the oil will cause a reduction in blood pressure and may make you dizzy.   It will normalize the blood pressure though when the proper levels are achieved.   Unlike some websites are reporting, it does not affect the pressure of those with low blood pressure.

According to Web MD, they have no information of any drug interactions at present.

I caution all my readers to buy the best oils available.  There are several suggestions on the right side of the blog.  Take the dosage correctly, read my article on dosages.

Nebulizer Treatment for Bronchitis and Pneumonia Using Ionic Silver and Black Seed Oil

I had 3 cases of pneumonia in a row due to a stroke I had a few months ago.  They tell me this caused problems in breathing.  I tried many things to cure the pneumonia but none of them worked.

On one of my trips to a doctor, he hooked me up with a nebulizer machine and I felt immediate relief.  So I told him to bring me one.

A few days later, the doctor still did not come to my home with the nebulizer and so I purchased one at my local Pharmacy.  It was from Philips Compressor, a very good brand and the price was reasonable too.

 So I asked what kind of medicine I needed to go with the nebulizer and he gave me the best one they had called Ventolin.  The problem was he did not tell me the nebulizer solution needed to be diluted.  So I added the solution to my brand new machine and I overdosed quickly.  My entire body was having mass tremors.

I called my doctor and he told me I had to get to the hospital as I would go into cardiac arrest.  So I called an ambulance and my neighbor and had one of the worse nights of my life.

Ambulance Drivers are not Nice

Keep in mind I live in Jordan and not for sure if all ambulance drivers are the same, but this one was awful.  His main concern was where was I from, how old was I and did I have children.  He did not even want me to lay down in the bed.  I told him I was going to report him for his bad behavior too.

I finally got to the hospital and went through all the check in and met my doctor and he told me that I did not need to come.  He wanted to know who my doctor was that sent me there.  I finally got home at 3am and just wanted to see my cats.

After a few days I went to the pharmacy to complain and find out how to mix the medicine.  In the meantime I talked to a man on Curezone about Ionic Silver and using it in a nebulizer.   He told me to use it full force or with Mullein oil for the mucus.  I chose to use it full force and it cleaned out my nostrils well.

Testimony for Nebulizer

Tony Isaacs, left me a testimony to show what he did to help a woman with pneumonia.  Here is what he said:

A few weeks ago a friend on Facebook wrote that she had a horrible bronchial infection and could barely breath. I suggested that she get a nebulizer and mix 5 parts Colloidal Silver to 1 part lobelia extract and 1 part mullein extract. I also suggested that she get a Chinese herbal formula known as ClearLungs. This is a combination I have personally used and seen others use many times with great success.  Actualy it is not colloidal silver, but ionic silver.  Ionic silver is 10,000 times stronger than colloidal silver.   Read here on ionic silver potency.

A few days later, here is what she wrote me:

"I just wanted to let you know how much better I feel. Quit the inhalers and nasty medicine for the nebulizer I was prescribed and just stuck to your program. I do a mister with distilled water also and feel so cured. That growth that was blocking feels almost non existent now. I will continue the program until I visit the horse doctor or the oncologist so they can listen to how clear my lungs are. God bless you my friend.


So I looked online for the products I needed and a thought came to me, why not just add black seed oil to my ionic silver.  So I added a few drops of black seed oil to the ionic silver from Soverign Silver and began my nebulizing treatment.  Sure enough in around 8 minutes of treatment, I could breathe well and I felt satisfied.

In the evening I decided to compare the Ventolin to the black seed oil.  After the treatment my entire windpipe swole up and I had a major panic attack.  I did not know how to breathe and it was 2am in the morning.

I found some essential oils and put them in my Now Diffuser and turned that on and went to rest.  By the morning I could breathe again and I knew then I would never use that stuff again.  The next day began again my black seed oil treatments in the nebulizer and I continued to improve daily. 

I have never gone back to the meds and instead use my treatment with ionic silver and black seed oil.

Research Shows the Effect of Nigella Sativa on Brain Injuiry and Edema

I recently had another stroke and one of the things I personally used was Nigella Sativa internally and topically for numbness.  I also drank cayenne tea as recommended by Dr. Christopher.   

Background & objectives: Stroke is third leading cause of death and disability in the most of human communities. The use of herbs and medicinal plants in different countries is increasing. Today, herbal medicine is used as alternative or complementary therapies with a fewer side effects. Nigella sativa has a rich medical and religious history. Oxidative stress has important role in the pathophysiology of stroke. As Nigella sativa has antioxidant effects, its administration may produce a protective effect against complications of this disease. We examined the effects of the treatment with Nigella sativa oil on the cerebral infarction and edema.

Methods: 48 Male Sprague-Dawley rats were divided into three groups, sham, control ischemic and Nigella sativa oil treated (2 ml/kg) ischemic groups. Transient focal cerebral ischemia was induced by 90-min-long occlusion of the left middle cerebral artery followed by 24-h-long reperfusion. Neurological deficit score was evaluated at the end of the reperfusion period. Thereafter, the animals were randomly selected and used for two projects: (i) Measurement of the infarct volumes and neurological outcome (ii) investigation of ischemic brain edema formation using a wet/dry method.

Results: Induction of cerebral ischemia in the control group produced considerable brain infarction in conjunction with impaired motor functions and severely brain edema. Treatment with Nigella sativa oil significantly reduced the infarct volume and improved the motor functions. The water content in the left (lesioned) hemisphere was considerably elevated in the control ischemic group. Administration of the Nigella sativa oil significantly lowered the water content in the ischemic lesioned hemisphere.

Conclusion: Treatment with Nigella sativa oil can noticeably decrease the ischemic brain injury, attenuate edema formation and improve motor disabilities.
