What is Bael Leaves?

Benefits of Bael Leaves

Bael leaves, also known as bilva patra, are the leaves of the Aegle marmelos tree, a deciduous tree native to India and Southeast Asia.

According to extensive experimental and clinical studies published in the Asian Pacific Journal of Tropical Disease, Bael is a reputable herb with antidiarrhoeal, antimicrobial, antiviral, radioprotective, anticancer, chemopreventive, antipyretic, ulcer healing, antigenotoxic, diuretic, antifertility and anti-inflammatory properties, and may play important role in prevention and treatment of a wide range of ailment [2].

These leaves have been used in traditional Indian medicine for centuries for their various health benefits [3]. Bael leaves are typically consumed in the form of a decoction or powder.

Whether consumed as a decoction or powder, bael leaves gently yet effectively address a multitude of health concerns.

Their antispasmodic and astringent properties soothe digestive distress, while their anti-inflammatory effects bring relief to a range of ailments.

Moreover, bael leaves have demonstrated remarkable efficacy in lowering blood sugar levels, improving insulin sensitivity, and safeguarding cardiovascular health.

Bioactive Compounds

Bael leaves are rich in various bioactive compounds [4], including:

  • Alkaloids: These compounds have antispasmodic, anti-inflammatory, and analgesic properties.
  • Flavonoids: These compounds have antioxidant and anti-inflammatory properties.
  • Phenolics: Compounds with antioxidant and anti-inflammatory
  • Coumarins: These compounds have anti-inflammatory and anticoagulant properties.
  • Tannins: These compounds have astringent properties.

Health Benefits of Bael Leaves

Bael leaves have been shown to offer a variety of health benefits as outlined below:

1. May help treat Alzheimer

The results from an In vitro study suggest that the ethyl acetate fraction of bael leaves is a potential source of natural antioxidants and may be useful in the treatment of Alzheimer’s disease.

During the experiment the ethyl acetate fraction of bael leaves exhibited the highest inhibition of AChE activity, reducing activity, and radical scavenging ability. It also displayed higher inhibition of brain lipid peroxidation.

This also shows that the ethyl acetate fraction contained higher contents of phenolics and flavonoids than other fractions which made it a potential candidate for Alzheimer’s treatment, as well as to combat free radicals [5].

However, there is a need for an in vivo study on this, to determine the actual effect and mechanism of action on real-life animals.

2. May help combat stress

Not the leaves but the dried fruit extract of bael possess adaptogenic properties and may help combat stress.

According to a study [6] that investigated the anti-stress, and adaptogenic activity of the dried fruit extract of bael using rat model by accessing their swimming endurance and post-swimming motor function, cold swimming endurance, and forced swim tests in rats.

The extracts showed the presence of phenolics, flavonoids, carbohydrates, and volatile oils in preliminary phytochemical screening.

In the forced swim test, the extracts did increase their swimming endurance time, post-motor function, and cold swimming endurance time, this suggests that the extracts could also reduce the level of stress markers during stressful activities.

3. Help manage diabetes

Bael leaves have been shown to lower blood sugar levels and improve insulin sensitivity.

A study to determine the potential therapeutic effects of bael leaves aqueous extract on diabetes mellitus found that feeding rats with an aqueous extract of bael leaves significantly lowered blood glucose levels in alloxan-induced diabetic rats [7].

This suggests that Bael may have anti-diabetic properties. Additionally, the extract did not cause any significant changes in body weight in non-diabetic rats, suggesting that it may be safe for long-term use.

4. Natural birth control remedy

Bael leaves have been shown to have a reversible antifertility potential and may be used as an effective agent for natural birth control.

In several scientific studies, barl leaf extract demonstrated its antifertility effect by temporarily reducing spermatogenesis [8, 9, 10].

However, the experiment was on animals, and its impact on humans is still unknown, hence more studies are needed.

5. Help fight inflammations

Bael leaves have anti-inflammatory properties that can help to reduce inflammation throughout the body.

According to reports, leaves of bael contain compounds that possess anti-inflammatory, antinociceptive, and antipyretic properties.

These properties were evaluated by several studies using various experimental models in animals [11, 12].

The extracts derived from the leaves significantly inhibited carrageenan-induced paw edema and cotton pellet granuloma in rats, indicating their anti-inflammatory activity [13].

Additionally, the extracts reduced paw licking in mice, suggesting their analgesic activity. Moreover, the extracts significantly reduced hyperpyrexia in rats, demonstrating their antipyretic property.

These findings highlight the potential therapeutic benefits of Aegle marmelos leaves in managing inflammatory conditions, pain, and fever.

6. May reduce the risk of cardiovascular disease

Due to its cardioprotective effects, a decoction made from bael leaves may lower the risk of cardiovascular disease, and improve heart health.

Bael leaves have been shown to lower blood pressure and cholesterol levels, reducing the risk of heart disease.

One animal study on toads suggests that the extract of bael leaves may be a good heart stimulant, as lower doses increased both HR and force of contraction, both in normal and hyperdynamic heart models [14].

However, a study on humans is needed to verify if it has the same effect on humans.

Hyperlipidemia a condition where there is a high level of fat particles lipid in the blood, may cause death if not treated on time.

However, according to a 21-day study on the rats model, the control and experimental group was fed leaf extract of Aegle marmelos (bael leaves) and Camellia sinensis (tea leaves) [15].

The result showed a significant decrease in the ACAT, and HMG-CoA reductase levels, and a significant increase in high-density lipoprotein levels, which further proves that the leaf extract of the two plants may help in managing hyperlipidemia and cardiovascular issues.

However it was not clear which particular plant among the two used is more effective, secondly, human-based study is required to understand their effects on humans.

7. Antimicrobial effects

Bael leaves have been shown to have antimicrobial activity against bacteria and fungi.

Bael has a traditional reputation in India for its use in treating several ailments, especially against bacteria [16]. A study investigated the phytochemical content and antibacterial activity of 18 varieties/accessions of A. marmelos.

The Pant Aparna variety showed the highest concentration of alkaloids, flavonoids, and phenols.

The aqueous extract exhibited the strongest antibacterial activity against S. epidermidis, while the methanolic extract was most effective against S. aureus. The GC-MS analysis revealed the presence of various bioactive compounds that could contribute to the antibacterial activity [17].

Bael leaves and fertility

Studies have shown that bael leaf extract has an antifertility property which may affect spermatogenesis.

A study on a rat model that was fed bael leaf extract at doses of 200, 400, and 600 mg/kg in an experiment. The results showed a significant decrease in sperm count in rats. The concentration of sperm in the epididymis and sexual behavior was altered [18].

Another animal study reported that intake of 300 mg/kg dose of bael leave extract daily for 60 days significantly impaired spermatogenesis, and caused a drop in sperm motility and concentration [19]. However, there was a complete restoration of sperm quality and sperm generation process after 120 days of withdrawing from taking the extract.

Also, one animal study that experimented with a methanolic extract from the bark of a bael tree at the dose of 200, 400, and 600 mg/Kg per body weight for 60 days, reported a reduction in sperm density, motility, viability, and sperm acrosomal integrity without interfering libido and vital organ [20]

Summary: Both the ethanolic of the leaves and bark methanolic extract of (bael) Aegle marmelos a promising candidates for a male contraceptive due to its ability to effectively prevent pregnancy and rapidly restore fertility after treatment discontinuation. Additionally, it has been shown to have lipid-correcting properties, providing further potential health benefits.
