Betel Leaf: In Detail

Betel leaf is also referred to as ‘Green Gold.’ It is an ancient asset of Indian medicine (Ayurveda), and its use in India dates back to 400 BC.

Piper betle or betel leaf belongs to the Piperaceae family (the Black pepper family). There are about 100 varieties of betel vine in the world, of which about 40 are found in India. According to folk medicine, betel leaf can help in the treatment of headache, itching, mastitisⁱ  XA painful infection or inflammation of the breast tissue which causes breast pain, redness and swelling. , cuts, abrasions, constipation, and injuries (1), (2).

Trivia

Betel leaves grow on the betel vine that belongs to the same plant family as pepper and kava. Betel nuts, on the contrary, do not grow on the betel vine and instead are the fruits of the areca palm tree.

While its essential oil possesses antibacterial, antiprotozoalⁱ  XA class of drugs used to treat infections that are caused by protozoa, single-cellular organisms that cause tissue damage. , and antifungal properties, its leaves possess anti-inflammatory properties that may help in treating oral and dental issues (1), (2).

How Does Betel Leaf Benefit Your Health?

Contrary to popular belief, betel leaf offers several health benefits. It has a positive effect on blood glucose control, dental health, wound healing, and viral infections.

1. May Help Manage Diabetes

Red betel leaves may lower blood glucose levels. They contain active molecules called tanninsⁱ  XCommonly called tannic acid, it refers to polyphenols present in plant food that precipitate protein and have astringent properties. that have antidiabetic properties. Betel alkaloids can lower blood glucose levels by inhibiting glucose absorption in the intestine (3).

This leaf also contains a variety of polyphenols that have excellent antioxidant potential. These molecules protect the pancreatic cells from free radical damage.

In India, eating paan (betel quid) after meals is a common practice. Rat studies have proven that this practice can lower the biomarkers of hyperglycemia (high blood sugar) (3), (4).

2. May Promote Dental Health

Like tattoos, teeth blackening was a craze in Southeast Asia. It was done using plant extracts and minerals. This procedure is said to be good for your teeth. It can prevent oral infections and painful dental procedures (5).

Betel vine is one of the plants linked to teeth blackening. A betel quid made with areca nut, slaked lime, and betel leaves has similar properties (5), (6).

However, betel leaf also releases catecholaminesⁱ  XA class of aromatic neurotransmitters that provide significant responses during stress. This includes hormones, such as adrenaline. that interact with the compounds released by areca nut and slaked lime. This, in turn, can cause oral and throat cancers (5), (6).

Quick Tip

Instead of chewing betel leaves as they are or chewing on potentially dangerous betel quids, you can add chopped betel leaves to your salad to add texture and enjoy their characteristic peppery flavor.

3. Accelerates Wound Healing

High oxidative stress, i.e., free radicals in your body, can delay wound healing. Delayed wound healing is one of the critical complications seen in type 1 diabetes. Herbal extracts of betel leaf may be effective in treating such sensitive cases (7).

Betel leaf contains polyphenols that have antioxidant properties. They boost the activity of the free radical-scavenging enzymes in your body, like superoxide dismutase and catalase (7).

Applying its extract to wounded rats increased the rate of wound healing. It boosted the content of hydroxyproline, a major component of collagen in these rats. Higher collagen content facilitates rapid wound repair and tissue regeneration (7).

4. May Reduce Cough And Congestion

According to traditional medicine, betel leaves can relieve cough. These leaves are soaked in mustard oil, warmed, and applied to the chest to ease congestion in the lungs (8).

Betel leaf juice with honey can be given to children to get rid of phlegm and wet cough, thanks to its warm and spicy flavor. Literature suggests that this plant can treat bronchitisⁱ  XInflammation of the bronchial tubes that carry air to and from lungs. Its symptoms include coughing and shortness of breath. too. Its essential oils are thought to play a vital role in this property (8), (9).

5. May Help Combat Cancer

This leaf contains a high amount of a carcinogenⁱ  XA substance, agent or organism naturally present in the environment that has the potential to cause cancer. called safrole. However, it gets metabolized to dihydroxychavicol and eugenol. Both of these compounds are excreted via urine (1).

Betel leaf exhibits antioxidant, antimutagenicⁱ  XThey are agents that interfere with the mutagenicity of a substance and help reduce the rate of mutations. , and anticancer properties. The betel phytochemicals are responsible for these properties. This means betel quids may not be cancer-causing at a non-addictive level of consumption (unless you make them with tobacco). Tobacco quids are linked to oral cancer (1).

In fact, the compounds in betel leaf – hydroxychavicol and chlorogenic acid – counter the carcinogens from tobacco. They can selectively kill the cancerous cells without affecting the healthy cells, unlike common cancer drugs and relevant therapeutic procedures (1).

That’s how betel phytochemicals protect your organ systems. It can also be used as a stimulant, antiseptic, breath freshener, or a mouthwash to treat oral fungal infections (2). Also, it is a carminative agent and a metabolism booster, which may also help to improve digestion (10), (11).

However, there’s a lot written about the side effects of betel leaf as well. Many studies paint this plant in a poor light. Scroll down to the next section to find out more.

What Are The Side Effects Of Betel Leaf?

When you chew a betel leaf, it releases certain active chemicals like catecholamines. These chemicals interact with other secretions of areca nut and slaked lime if you have a betel quid. These chemical interactions may cause serious side effects (12), (13), (14), (15):

• May have psychoactiveⁱ  XThese are substances that can change functions of the nervous system and alter mood, perception, consciousness, and behavior. properties
• Affect your central nervous system (CNS)
• Cause mouth and esophageal (food pipe) cancer
• Disturb your oral microbiome (the good microbes in your mouth)
• Can have a negative impact on pregnancy, childbirth, and fetal development
• Linked to addiction and withdrawal issues

Moreover, a definite daily intake limit for betel leaves has not been scientifically established yet.

Due to these hazardous effects, the World Health Organization (WHO) has publicly stated that betel quid products are a health threat to those consuming them (14).
