What are the health benefits of garlic?

1. It helps lower blood pressure 

Garlic has been known to lower blood pressure thus preventing cardiovascular diseases such as heart attacks and strokes. Human studies have shown that garlic quickens the synthesis of nitric oxide which dilates blood vessels and suppresses angiotensin-converting enzyme (ACE) activity. This has the potential to reduce high blood pressure. It also prevents blood platelets from sticking to the artery walls.


Another fruit know to be good for hypertensives which also helps protect against cardiovascular diseases is Jackfruit.

2. It improves the immune system

Garlic contains antibacterial and antiviral properties that help fight and prevent viruses and bacteria from affecting the human body. It does this by blocking the entry of viruses into cells and bolsters the immune system’s response to attacks. It is also known as an infection fighter.

3. It contains vitamins and minerals

Vitamins and minerals are nutrients that the body needs in small amounts to stay healthy and function well. Garlic gives a bonus because it contains vitamin B6 (Pyridoxine) which is needed for normal brain development, and for keeping the nervous system in good shape.

4. It has the potential to lower cholesterol

Studies conducted have shown that garlic has the potential to lower cholesterol. It is low in calories and also it contains a compound called allicin which can reduce LDL (low-density lipoprotein) cholesterol (which is also known as bad cholesterol because it collects in the walls of your blood vessels, thus, increasing your chances of health problems such as heart attack or stroke).

5. Control asthma

Another health benefit of garlic is that it can control asthma. Eating boiled garlic flower buds or cloves is an effective remedy for reducing the symptoms of asthma. Another remedy is drinking a glass of milk with boiled garlic cloves before going to bed. This has been known to bring alleviation to people with asthma.

6. May have anti-cancer activity

The compounds contained in garlic have been studied. This is because these compounds can constrain cancerous cells and block or stop tumour generation.

7. Works as an anti-inflammatory agent

Studies have shown that garlic oil possesses anti-inflammatory effects. If you suffer from inflamed joints or muscles, smear them with the oil. The Arthritis Foundation recommends it to help prevent cartilage damage from arthritis.

The athlete’s foot (tinea pedis) is a fungal infection that occurs between the toes. It commonly occurs in people whose feet have become very sweaty while confined within tightfitting shoes. Signs and symptoms of an athlete’s foot include a rash of scaly nature.

Garlic is also known to fight fungus. Soaking an athlete’s foot in water mixed with garlic or rubbing your foot with garlic attacks the itch fungus.

9. Gives better hair and skin

The antibacterial traits of garlic can make your skin glow by clearing the skin of acne-causing bacteria. Studies have shown that rubbing garlic over pimples can wipe them away. Although it can cause a burning sensation if a person’s skin has an allergic reaction to garlic, one must be cautious when trying this method or seek professional help from a dermatologist.
