The natural tree extracts neem oil in cosmetics, medicine, and other agricultural processes. While much praised elsewhere, neem oil has been prohibited in Canada because of safety concerns.

But what are these adverse effects of neem oil?

Take more than the recommended amount. You could experience adverse side effects such as kidney damage, low blood sugar, decreased fertility, allergic reactions, overstimulated immune system, and stomach irritation.

That said, here are 9 comprehensive reasons why neem oil is banned in Canada.

1. Possibility of Causing Harm to the Kidneys

According to a new study, the use of Chinese herbal treatment has been linked to a case of acute kidney failure in a human.

According to the research, neem was a significant component in the damage. Even though there is no reasonable connection between neem consumption and renal impairment, caution is warranted.

Toxic kidney damage from herbal remedies is rising, and this trend is expected to continue. Therefore, be careful.

Some research also suggests that consuming too much neem can harm the liver. If you suffer from liver problems, it’s best to get the OK from a doctor before using neem.

2. Dangerously Reduces Blood Sugar

Combining neem with lifespan spinach (a variety of spinach ordinary in China) has been shown to have hypoglycemic effects.

Although neem’s hypoglycemic properties are appealing, those already taking drugs to control their blood sugar levels should talk to their doctor before using neem as a dietary supplement.

Small doses of neem oil help regulate blood sugar; thus, doctors recommend it for people with diabetes. But the decline may become severe with prolonged use. Hypoglycemia can lead to exhaustion and fainting (fatigue).

3. Possible Effects On Fertility

Neem flower extracts were found to inhibit ovulation in rats. Neem has potential as an antifertility agent, but it may also have unintended consequences.

Tests on rodents, rabbits, guinea pigs, and other small mammals showed that neem oil significantly decreased sperm production in males. Six weeks was enough time for a 67% decrease in male rats in the research.

On the other hand, neem did not appear to inhibit sperm development.

Some farmers employ neem pesticides to render pests sterile so they do not reproduce. This sterile effect can be replicated on humans who come into contact with the chemical.

These chemicals are toxic to the immune system and have been shown to alter the sperm’s natural movement. However, there is a shortage of studies addressing this issue.

4. Could Possibly Lead to a Miscarriage

Pregnancies in rodents and monkeys could be terminated with the extracts with no noticeable negative consequences.

If you’re trying to get pregnant, you might want to avoid taking neem, but it could be helpful if you’re trying to abort the baby.

Overexposure to neem has been hypothesized to trigger an overactive immunological response. Because of this, the embryo may develop without sperm cells. But there isn’t enough evidence to support this.

5. A Possible Allergy Trigger

The incidence of immediate allergic stomatitis (mouth irritation) following weekly ingestion of neem leaves for three weeks is shown in available research.

Even though neem is used to alleviate hay fever symptoms and other allergic reactions, prolonged exposure to the herb can trigger an allergic reaction.

After a patch test, individuals who have an allergy to neem oil could get hives or a rash. More research is required to see if neem causes any additional types of allergies.

6. A Possible Cause of Infant Deaths

There is evidence that neem can be harmful to newborns. Infant deaths have been linked to low neem oil dosages (5 ml).

The lethality of neem oil was demonstrated in animal tests at dosages as low as 12–24 ml per kg of body weight.

More research is needed to determine if the pollutants may have brought these effects in neem oil rather than neem itself.

Long-term use of neem leaves or neem extracts is not recommended. There have been anecdotal cases of renal failure in people who used neem leaf tea as a malaria remedy.

7. Potential to Irritate the Stomach

Indigestion and stomach discomfort have been linked to excessive inhalation and intake of neem.

Hydrochloric acid within the stomach can be lowered by taking neem extracts. It has been found that neem extracts are effective in treating gastritis.

The antibacterial and anti-inflammatory characteristics of the extracts help alleviate the symptoms of this ailment and lower stomach acidity. All these effects, however, may lead to stomach irritation.

8. Your Immune System Could Be Overstimulated

The immune system can be strengthened through neem or its-based products. However, excessive neem use (particularly by sick people) might overstimulate the immunity system and lead to unwanted side effects.

Patients who have received an organ transplant may also need to avoid neem. The leaves may negatively interact with immunosuppressant drugs used in surgical procedures.

But there isn’t nearly enough data to make that claim with confidence.

9. Classified as a toxicity chemical

Generally speaking, neem oil is safe to use. For some, it may trigger an allergic reaction, most notably contact dermatitis. Despite this, the EPA classifies the oil as a “low toxicity” chemical.

In addition, small doses of neem oil are probably safe for ingestion, but large amounts can have negative consequences, especially for children. The oil may lead to:

  • Nausea and vomiting.
  • Symptoms of metabolic acidosis.
  • The disease of the brain (also known as encephalopathy).

Bottom line

Neem has tremendous and far-reaching advantages. Overall health can be improved by taking it in the recommended dosages.

Neem oil can moisturize your skin, lighten scars, remedy injuries, improve the body’s collagen production and solve the problem of acne.

It is particularly harmful to young children and pregnant mothers. Consumption of it should therefore be approached with extreme care.

More research is required to fully understand the effects of neem oil on the scalp and hair.

It’s possible that neem is safe to try as a generic booster.

Before using it to treat systemic inflammation, parasitic infections, or any other underlying issue, you should consult a doctor.
