But if you want to know which ones are the absolute worst, then this list is a good place to be. Read on about the specific "health" trends on the massively social media platform that you should avoid at all costs.

'Benadryl Challenge'

Let's start off with something gruesome enough to have claimed one person's life, according to HealthDigest. 

Back in 2020, the so-called "Benadryl Challenge" made the rounds on TikTok. It asked users to take at least a dozen doses of the popular antihistamine drug Benadryl, in order to induce a "trip" (aka hallucination). A teen girl from Oklahoma participated and died of a subsequent overdose afterwards.

While some may consider antihistamines as relatively mild drugs, taking too much of it can be as fatal. Experts say that large doses of Benadryl can be potent enough to cause seizures and heart problems. It will generally cause arrhythmia (irregular heartbeat), which will then lead to the organ not pumping blood effectively throughout the body.

Just don't do it for your sake.

Garlic Cloves Up Your Nostrils To Clear Your Sinuses

FoodNetwork mentioned another specific "health" trend on TikTok that had people jam garlic cloves up their nostrils. The reason? It could apparently clear a stuffy nose, with some people even claiming that it is a completely safe thing to do. It is not, and not even by a longshot.

Some YouTube videos tell women to put garlic in their vaginas. Gynecologist Jennifer Gunter cited reasons why it is not a good idea to place garlic in the private parts to treat an infection.

This is due to garlic's natural oils that can irritate the sensitive skin around your nose. Furthermore, a small-enough clove can get lodged up in there, causing a major nasal blockage and a trip to the emergency room. Stick to using garlic in your food.

At-Home Mole Removal

In just another dangerous TikTok health trend, people are attempting to remove their moles at home using a variety of substances and items. One method involves using chemicals like eyelash glue, which they say would help remove the mole.

Speaking to the BBC, British Skin Foundation spokesperson Dr. Adil Sheraz stated that eyelash glue's main ingredient, cyanoacrylate, is classified as a "contact allergen." Using this to remove a mole will likely cause a "plumping effect" that can leave you permanently scarred or even disfigured.

If you want to remove a mole, only consult with an accredited dermatologist.

Drinking Water Laced With Chlorophyll

This particular trend apparently got so big, even celebrities were into it. TikTokers were reportedly swearing by it because it "stimulates" the immune system and could even detoxify your blood or prevent cancer. Of course, this is hogwash with very little scientific basis.

Putting drops of chlorophyll into your drinking water can, in the long-term, cause dermatitis, stomach aches, and even light sensitivity, writes FoodNetwork. The dangers are also even more pronounced if you're pregnant and breastfeeding.

Why Are A Lot Of TikTok Health Trends So Bad?

TikTok health trends can be started by literally anyone. That's the appeal of TikTok as a whole in the first place. You don't have to be an actual health expert to claim that you have a "health hack," because one way or another, the social media platform's algorithm will make your video popular enough to be shared millions of times.

An Indian mobile user browses through the Chinese owned video-sharing 'Tik Tok' app on a smartphone in Bangalore on June 30, 2020. - TikTok on June 30 denied sharing information on Indian users with the Chinese government, after New Delhi banned the wildly popular app citing national security and privacy concerns.

Unless you know that the tip comes from a reputable, actual health professional, just don't follow it. That's the simplest way of avoiding any trouble.
