The Health Benefits of Loquat leaves
Living in a part of the world where loquat is grown, I was more familiar with loquat as a tasty, juicy fruit than with the medicinal properties of its leaves. However, a little research tells me that we should not be so quick to dismiss the other parts of the tree and that we can make plenty of use of its leaves which have a variety of proven benefits for your health.
The tree which bears the delicious loquat fruit is an evergreen native to China and Japan but now grown in many parts of South East Asia. Also known by its scientific name ‘Eribotrya japonica’ the tree produces an orange plum shaped fruit with a taste and consistency similar to a hybrid of a peach and a mango.
The fruit is eaten alone either fresh or dried but is also used to make delicious jams. While many people will be familiar with the fruit, fewer are aware of the many benefits that can be taken from its leaves.
The Japanese in particular use the leaves to make a healthful tea while it is also possible to make healing ointments and poultices from the crushed and ground leaves before applying it to treat minor wounds.
Loquat Nutritional Value
Both the loquat fruit and its leaves contain a rich variety of important vitamins and other nutrients. These include pectin, potassium, iron and fiber as well as vitamins A and C.
This diverse array of vital nutrients is excellent for general health purposes but loquat leaves also confer certain specific health benefits that we will look at in detail below.
Loquat Leaf Health Benefits
Loquat leaves have been fairly well studied over recent years and research has revealed that many of its health benefits are related to its powerful antioxidant capacity.
By now, most people are aware of the importance of getting as many natural antioxidants into our system as possible in order to prevent the free radical damage that wreaks havoc on our health and leads to serious illness.
As well as their antioxidant activity, loquat leaves contain triterponoid acid which can help reduce swelling and redness on the skin. The benefits of the loquat leaf include the following:
1) For Diabetes
One of the most significant findings regarding loquat leaves is that it might help the body to combat diabetes. It has anti diabetic potential because the leaves produce chemicals known as triterpenes including an acid called tormentic acid.
Research has demonstrated that tormentic acid can increase the body’s production of insulin which may help combat the symptoms of diabetes. (1)
In addition, the Chinese Government has approved the use of loquat leaves to support blood-sugar levels because they help produce polysaccharides which are known to stimulate the production of insulin in the pancreas.
2) For Liver Support
Your liver is the body’s powerhouse when it comes to eliminating harmful toxins from the body. Sometimes your liver gets overloaded with work and needs help in order to perform its important functions as well as possible.
Loquat leaves can help because they contain an antioxidant compound called Amygdalin which can support the liver and help it function better. In addition, research shows that loquat leaves are a rich source of plant sterols linoleic acids which help the liver perform properly. (2)
3) For Respiratory Health and Allergies
One of the traditional uses of loquat leaves was as a natural remedy for a variety of respiratory problems including congestion, coughing, allergic reaction and lung irritation. Recent scientific research has gone some way to confirming that this historical use had merit.
A study published in 2009 found that when rats were fed with loquat leaf they experienced a slower allergic reaction than those not given the leaf. (3)
Other experiments on animals have found that loquat leaf had a natural anti-histamine effect and reduced sneezing. (4)
Another study published in the same year found that loquat leaves helped reduce redness and inflammation by disrupting the communication of the swelling response after cells have detected an allergen. (5)
Drinking a nice soothing cup of loquat leaf tea also has an expectorant effect which means it helps loosen mucus and relieve congestion helping you to breathe more freely.
4) For Eczema and other Skin Complaints
Loquat leaves can be applied topically in cream form as a remedy for redness and irritation caused by environmental allergens especially when the reaction is caused by histamines. (6)
When applied topically, loquat leaf can combat the reaction from histamine production which both soothes inflamed skin and helps general skin health.
Drinking loquat leaf tea can provide general skin benefits because of its antioxidant and anti-inflammatory ability while it can also help soothe painful and inflamed gums. (7)
5) For Brain Health
Experts believe that oxidative stress as a result of free radical exposure is one of the main causes of neurological degeneration. Because of its powerful antioxidant effects, loquat leaves may prove beneficial in maintaining brain health.
A study published in 2011 demonstrated that mice fed with extracts of loquat leaf exhibited significant improvements in memory tests suggesting that it helps protect against oxidative damage. (8)
6) For Colds
There is scientific evidence that loquat leaf has antiviral properties as a result of antigens produced by the acids in the leaf. In addition to these antigens, the triterpenes contained in the leaf might help to protect against the cold. (9)
7) Bone Strength
As we age, our bone density becomes lighter and our bones become weaker. This is especially the case in women following the menopause because of the reduced level of estrogen in their bodies. Recent research shows that loquat leaf tea may help combat bone loss from estrogen depletion.
In a study published in 2014, mice whose ovaries had been removed were fed loquat leaves which resulted in a significant improvement in bone density in the lumbar area, head and abdomen.
How to make Loquat Leaf Tea
Loquat tea is a popular traditional Japanese drink which they call Biwa Cha. It is simple to make and has a mild and pleasant flavor to go along with its multiple health benefits and can be enjoyed either hot or cold.
Commercially the leaves are picked when they are green before being washed, cleaned and dried. After drying, they are chopped up into pieces ready to be brewed.
Loquat leaf tea is easy enough to make yourself at home provided of course that you can get hold of the leaves. The following is a traditional Japanese recipe for loquat leaf tea.
- Cut the leaves into finger width strips.
- Add 5 grams of leaves to 4 cups of water then bring them to a boil in either a kettle or a pot.
- Turn down the heat and let it simmer for between 10 and 15 minutes.
- Turn the heat off and allow the tea to steep for a further 10 minutes.
- Strain the tea, serve and drink up.
Loquat Leaf Side Effects
Loquat leaves appear to be safe and no toxic effects have been found in the studies published so far even at very high doses.
There is one isolated report of a 39-year-old male who developed toxic myopathy after drinking 2 liters of loquat leaf extract for 2 weeks. Toxic myopathy is characterized by muscular pain and weakness.
Despite this isolated incident, loquat leaf tea would appear to be safe for the vast majority of people with a very small risk of any adverse effects.
