Symptoms of garlic poisoning in humans
Garlic is one of the many foods that, when consumed in
excess, can be hazardous and harmful to your health.
Garlic is tasty and has a strong, pungent taste. This herb
has therapeutic qualities. However, have you ever considered the negative
consequences of garlic?
This article examines the 14 negative effects of garlic and
suggests precautions to take before taking it. Let's begin.
WHAT ARE THE KNOWN SIDE EFFECTS OF GARLIC?
1. May
result in liver damage
The liver may be harmed by consuming too much garlic.
Although raw garlic has antioxidant potential, too much of it can poison the
liver (1). According to research done on rats, taking garlic at high dosages
(0.5 grams per kg of body weight) can cause liver damage. Garlic is healthy for
the liver in little dosages, though (0.1 to 0.25 grams per kg of body weight
daily).
2.
Potentially Harmful Odor
Two of the most frequent side effects of garlic, according to an Italian investigation, were body odor and garlic breath (3). Body odor can also occur from consuming garlic, so it's not just a problem of poor personal cleanliness.
It has been observed that garlic breath persists in the
mouth for some time after brushing. According to some professionals, the same
compounds that make garlic beneficial and what cause it to cause foul breath
are the same chemicals (5). It might be embarrassing, nevertheless, to have foul
breath. So, before taking garlic, you should probably think again. Use a
mouth-refreshing spray as an additional precaution.
According to anecdotal data, eating raw garlic bulbs on an
empty stomach may result in nausea, vomiting, and heartburn. Garlic consumption
has been linked to heartburn and nausea in certain observational studies (6).
In certain people, excessive garlic consumption might lead to GERD
(gastroesophageal reflux disease). To fully comprehend this negative effect of
garlic, more study is required.
4.
Might Lead to Diarrhea
Overeating fresh garlic might make you sick. Garlic might
result in flatulence and diarrhea
5.
Might Lead to Gastric Problems
A polymer barrier is applied to enteric-coated garlic
products in one Japanese study to prevent disintegration in the stomach
environment. After consuming these garlic items, the mucous membrane of the
stomach became red (8). The findings imply that garlic use and related items
should be avoided since they may negatively impact stomach health.
Contrary to widespread perception, there is no proof that
eating garlic reduces the risk of stomach cancer.
Garlic might reduce blood pressure (10). However, it could
cause hypotension if you are currently taking drugs for high blood pressure
(low blood pressure). It has also been demonstrated that taking extra garlic
lowers blood pressure (11). Therefore, taking garlic supplements while also
taking blood pressure medicine may not be a good choice. Garlic taken orally
can also slightly lower blood pressure.
7. Can
Worsen Bleeding
The risk of bleeding may rise after using garlic. Warfarin
and other blood thinners should not be taken together as a result.
Particularly in the case of fresh garlic, this is true. It
is also preferable to cease consuming garlic at least seven days before to scheduled surgery. Garlic contains antiplatelet properties and could make
operation bleeding more pronounced.
8.
Might Cause Sweating
Garlic may, according to certain research, make some people
sweat excessively (15). More research is needed in this area, though.
9.
Might Make You Feel Dizzy and nauseous
Garlic consumption in excess can make you feel lightheaded
(16). This action's mechanism is still being investigated.
10. May
Lead To Eczema or Rash
Garlic can irritate the skin when in contact with it for an
extended period of time. This discomfort may be caused by some particular
enzymes in garlic. According to anecdotal evidence, eczema may also be a
disorder that comes along with this allergy.
As per
Stylecraze
Given that they all come from the same botanical family and
contain similar proteins, foods like onions, shallots, chives, and leeks may
cause an allergic reaction if you are allergic to garlic.
According to one study, using garlic for cooking on a
regular basis may cause skin rashes.
11.
Potential for Drug Interaction
One investigation discovered interactions between warfarin,
fluindione, ritonavir, and chlorpropamide as well as garlic and these drugs.
12.
Might Lead to Headache
Garlic, especially when consumed raw, may cause migraines
(19). It doesn't immediately create a migraine headache, but it does start the
process that does.
Though the precise cause of this is unknown, some
specialists think it might have something to do with the trigeminal nerve, the
primary pain pathway in the body. Garlic consumption may trigger this nerve to
release neuropeptides, which rush to the membrane encasing your brain and
create headaches.
13. May
Make Yeast Infection (Vaginal) Worse
Cloves of garlic may aggravate the vagina's delicate tissue
(20). To treat vaginal yeast infections, some women place garlic cloves in the
vagina. It is not advised to do this.
14. May Affect Vision
A disease known as hyphema, or bleeding inside the eye chamber
(the space between the iris and the cornea), has been reported to be caused by
consuming too much garlic (16). Garlic is an anticoagulant that can worsen or
cause hyphema when taken in high dosages. Additionally, hyphema may result in
irreversible eyesight loss.
Other negative effects of garlic may also exist, according
to anecdotal evidence. Appetite loss could result from excessive ingestion.
Kidney hematomas (swelling of clotted blood within kidney tissues), chemical
burns in the mouth, and potentially fatal allergic responses can result from too much garlic.
A disorder known as pemphigus, an autoimmune disease, may also
be brought on by garlic.
A list of items is available that, when combined with
garlic, may have negative consequences. These have been covered in the section
that follows.

Too much garlic consumption might have negative effects. How

The clinical dietitian at Memorial Regional Hospital South,
Jesse Feder, asserts that garlic is not poisonous. Nonetheless, consuming no more than 1-2 raw garlic cloves is generally advised each day.
CONCLUSION
Garlic side effects are mostly linked to long-term overconsumption.
Excessive amounts of garlic may cause liver damage, as well as nausea,
vomiting, heartburn, foul breath, gastrointestinal problems, perspiration,
dizziness, migraines, visual disturbances, and yeast infections. Moreover, it

chestnut, ginger, and ginkgo. Yet, consuming garlic in moderation has
significant advantages.
