Morus Alba (White Mulberry): Overview
Morus alba, commonly referred to as white mulberry, is a deciduous tree that can reach heights between 10 to 20 meters.
It has a notable light-colored bark, often grey or yellowish, which becomes deeply furrowed with age.
The tree’s leaves are its hallmark, varying greatly in shape, from heart-shaped to oval, and sometimes lobed.
They are bright green, glossy, and have a smooth texture, with a slightly paler underside.
The tree produces small, inconspicuous flowers which are grouped in catkins and are generally wind-pollinated.
Morus alba’s fruits are aggregate fruits that closely resemble blackberries.
Historical Context & Global Spread
Originally from China, Morus alba has been an integral part of Chinese culture and economy for thousands of years, primarily due to its role in sericulture.
The cultivation of Morus alba for silkworm feeding fueled the silk industry, a major economic and cultural element in ancient China.
Over time, its cultivation spread along the Silk Road to other parts of Asia and eventually to Europe and North America.
Traditional Uses Across Cultures
In TCM, Morus alba is believed to benefit the liver and kidneys, with its leaves and fruit used to treat conditions like insomnia, dizziness, and premature graying of hair.
The root bark is known for its antipyretic and diuretic properties.
In Indian Ayurvedic medicine, Morus alba is used to treat cold, flu, and respiratory issues, reflecting its adaptogenic qualities.
It’s also used in Korean and Japanese traditional medicine for similar purposes, including as a blood tonic and an agent to improve vision.
Culinary Uses & Nutritional Value
Apart from its medicinal applications, Morus alba holds a significant place in culinary traditions.
The fruits, with their sweet and slightly tart flavor, are consumed fresh, dried, or used in making jams, pies, wines, and teas.
In some cultures, the young leaves are also cooked and eaten as a vegetable.
Nutritionally, Morus alba’s fruits are rich in vitamins C and K, iron, potassium, and various phytonutrients.
They are also a good source of dietary fiber.
The leaves, often used for tea, contain compounds like flavonoids and antioxidants, contributing to their health benefits.
Morus Alba (White Mulberry): Phytochemicals & Mechanisms of Morus Alba
Morus alba contains a complex array of bioactive compounds, each contributing to its broad spectrum of medicinal properties.
Understanding these compounds in detail provides a clearer picture of how Morus alba operates at a molecular level to impart health benefits.
Flavonoids
Specific Compounds: Quercetin, kaempferol, rutin, and isoquercitrin are the primary flavonoids.
Mechanisms of Action
These flavonoids are powerful antioxidants, neutralizing free radicals and reducing oxidative stress, a key contributor to chronic diseases.
Quercetin, in particular, is known for its anti-inflammatory effects, inhibiting enzymes like cyclooxygenase (COX) and lipoxygenase (LOX), and blocking the production of inflammatory mediators like prostaglandins.
Rutin strengthens capillaries, which can be beneficial in conditions like varicose veins and hemorrhoids.
Alkaloids
Primary Compound: 1-Deoxynojirimycin (DNJ).
Mechanisms of Action
DNJ is a potent alpha-glucosidase inhibitor, effectively slowing down the breakdown of carbohydrates into simple sugars, thereby managing blood glucose levels post-meals.
This makes it particularly valuable in the management of Type 2 diabetes.
Phenolic Acids
Specific Compounds: Chlorogenic acid, caffeic acid, and ferulic acid.
Mechanisms of Action
These acids exhibit strong antioxidant and anti-inflammatory properties.
Chlorogenic acid, for instance, has been shown to modulate glucose and lipid metabolism, indicating potential benefits in metabolic syndrome.
Ferulic acid displays neuroprotective effects and might be beneficial in preventing age-related neurodegenerative diseases.
Anthocyanins
Specific Compounds: Mainly cyanidin-3-glucoside.
Mechanisms of Action
Apart from their antioxidant capabilities, anthocyanins in Morus alba have shown promise in reducing the risk of cardiovascular diseases by improving endothelial function and inhibiting LDL cholesterol oxidation.
Steroids & Sterols
Specific Compounds: β-Sitosterol and stigmasterol.
Mechanisms of Action
These compounds are known to lower cholesterol levels by inhibiting its absorption in the intestines.
β-Sitosterol also exhibits anti-cancer properties, especially against prostate and breast cancer.
Triterpenes
Specific Compounds: Betulinic acid and ursolic acid.
Mechanisms of Action
They have demonstrated significant anti-cancer activities, inducing apoptosis, and inhibiting metastasis.
Ursolic acid also shows promise in muscle and bone health, potentially beneficial in conditions like osteoporosis and sarcopenia.
