The myth: garlic should be eaten to cure ED

Mojo’s verdict: myth (there’s  evidence garlic has health benefits that could indirectly improve your erectile health, but there are better ED treatments out there)

Garlic is a staple ingredient used in most kitchens. According to mythology, you can use garlic to keep vampires away (unless biting’s your thing), to ward off evil spirits(1), and to treat erectile dysfunction (also known as ED or impotence). 

But can this food – known for its potent smell – really help with impotence? Let’s get into it.

Is it good to use garlic for ED?

No research has been done on garlic and erectile dysfunction specifically. 

But, research has proven that garlic has a range of health benefits. It can help reduce blood pressure, benefit blood flow, and improve heart health. Let’s take a closer look at the causes of ED, and the corresponding health benefits of garlic below.

The connection between garlic and erectile dysfunction

“Although no studies have proved that garlic can cure erectile dysfunction, garlic eaten as part of a healthy diet that can have a secondary effect on erectile dysfunction.”

Aron Snowsill, Nutritional Therapist

Garlic’s health benefits 

Reduced blood pressure

Some studies have found that garlic can lower blood pressure.(2) It is thought that 'allicin', a compound found in garlic, improves heart function, and helps to reduce blood pressure.(3)

Improved heart health and reduced cholesterol

Garlic contains substances(4) that have been shown to reduce the total amount of cholesterol in a person’s body.(5)

Increased blood flow

Allicin (the compound we were talking about earlier that reduces blood pressure), can also increase nitric oxide levels.(6) Nitric oxide helps blood vessels expand to promote better blood flow. 

"A small number of studies suggest that garlic might improve blood flow, which could, in theory, help with erections. But, more studies are needed, and it isn’t clear how much garlic would have a noticeable or consistent effect.”

Dr Matthew Chan, Medical Doctor

Lower levels of stress

In a study on mice, garlic was shown to significantly decrease stress-related hormones such as cortisol and the feeling of anxiety in mice.(7) In theory, garlic contains compounds that can help with stress responses.

All of these health benefits could indirectly impact your erectile health and therefore your erections. 

How to use garlic for erectile dysfunction

“Most doctors would not actively suggest garlic as part of a treatment plan. There are more proven treatments and lifestyle choices that doctors would suggest first, and are specific to the cause of the ED identified.

That said, if eating garlic seems to work well for you, it's unlikely that a doctor would stop you."

Dr Matthew Chan, Medical Doctor

If you’re using garlic cloves for your erection woes, keep in mind that there are more proven treatments. 

Erectile dysfunction treatments

Don’t worry, you don’t have to reach for garlic before a first date. The following treatments are all more researched, more effective, and more successful than garlic at beating erectile dysfunction.

Erectile dysfunction can be caused by psychological,  physical or lifestyle reasons. Depending on the root cause of your ED, treatment will be different.
