What are the morphological characteristics of this plant?

Morus alba has deciduous, alternate leaves that can vary from entire to lobed shapes, woody stems with grayish bark, and small, inconspicuous greenish flowers arranged in pendulous racemes. The leaf blades are typically ovate or heart-shaped with serrated margins and can reach lengths of up to 15 centimeters. Its branches are characterized by a spreading growth habit and a rough texture due to lenticels. The plant produces aggregate fruits known as mulberries that transition from green to white or red as they ripen. These fleshy drupelets are attached to a central core and serve as the primary reproductive structure of the species.

What is the geographical distribution of this plant?

This plant is native to a vast range spanning from China and Japan through the Korean Peninsula and into parts of Southeast Asia. Due to its long history of cultivation for silk production, it has been widely introduced to many other temperate and subtropical regions across the globe. It is now commonly established in North America, Europe, and various parts of Africa and South America. Many populations have become naturalized in these new environments, often spreading through bird dispersal of its fruit. Consequently, its presence is felt on nearly every continent where human agricultural activity has occurred.

How is this plant cultivated?

This plant Morus alba, commonly known as the white mulberry, requires well-draining soil and full sunlight to produce the highest quality fruit and foliage.

It thrives in most temperate climates and is remarkably adaptable to various soil types, including clay and sandy compositions. Regular watering is essential during the establishment phase, though mature trees are relatively drought-tolerant once their root systems are deep. Pruning should be performed during the dormant season to maintain a manageable size and encourage vigorous new growth.

Because it is a fast-growing species, it can quickly become a dominant feature in a landscape if not properly monitored.

What are the pharmacological activities of Morus alba?

This plant has pharmacological activities including anti-diabetic, anti-hyperglycemic, anti-hyperlipidemic, anti-oxidant, and alpha-glucosidase inhibitor properties. Its ability to act as an alpha-glucosidase inhibitor helps slow down carbohydrate digestion in the digestive tract. By managing glucose levels, the plant demonstrates significant anti-diabetic and anti-hyperglycemic effects. Additionally, its anti-hyperlipidemic activity assists in regulating lipid profiles within the bloodstream. These combined therapeutic actions are supported by its potent anti-oxidant capabilities which protect cells from oxidative stress.

According to a study published by "Yao xue xue bao = Acta pharmaceutica Sinica", the aqueous extract of Sangzhi from Ramulus mori was given orally to alloxan diabetic rats for 15 days. When these rats on high-calorie chow were treated with the extract, the hyperglycemic symptoms were improved and blood lipid levels were improved. The treatment also lowered the ratio of kidney over body weight and the blood N-acetyl-beta-D-glucosaminidase (NAG) activity. Additionally, the degree of renal pathological changes was significantly reduced. These results suggest that Sangzhi may be useful for treating diabetes and its complications.

The primary pharmacological activities of this plant are shown in the list below.

  • alpha-glucosidase inhibitor
  • anti-diabetic
  • anti-oxidant
  • anti-hyperglycemic
  • anti-hyperlipidemic

What medicinal compounds this plant contains?

This plant contains several potent medicinal compounds including 1-Deoxynojirimycin (DNJ), Kuwanon G, Morusin, Oxyresvatrol, and mulberry leaf polysaccharides. The alkaloid 1-Deoxynojirimycin (DNJ) is particularly noted for its ability to inhibit alpha-glucosidase, which helps manage blood sugar levels. Kuwanon G serves as another significant bioactive component that contributes to the plant's complex chemical profile. Morusin and oxyresvatrol provide antioxidant and anti-inflammatory properties that support cellular health. Additionally, mulberry leaf polysaccharides offer immunomodulatory effects that enhance the overall therapeutic potential of the species.

According to a study published by "Journal of medicinal food", Morus alba was identified as a lead medicinal plant after screening more than 8000 plants. Kuwanon G and Albanin G were isolated from the root-barks of Morus alba with 92% and 96% CB1 receptor ligand binding inhibitory activity, respectively. In acute food intake studies using oral doses of 250 and 500 mg/kg, food intake reductions of 58.6% and 44.8% were observed at 250 mg/kg, while 50.1% and 44.3% were observed at 500 mg/kg at 1 and 2 h postfood provision. A long-term study showed a 20% reduction in daily calorie intake. Obese mice treated with the high dose of Morus root-bark extract showed a 10.4 g (22.5%) loss in body weight compared to vehicle-treated animals and a 7.1 g (16.5%) loss compared to baseline at week 7.

The primary medicinal compounds of this plant are shown in the list below.

  • 1-Deoxynojirimycin (DNJ)
  • Kuwanon G
  • Morusin
  • Oxyresveratrol
  • Mulberry leaf polysaccharides

What health conditions is this plant used for?

This plant is used for managing Type 2 diabetes by regulating blood glucose levels and reducing hyperglycemia. The extracts from Morus alba help stabilize sugar concentrations in the bloodstream to prevent dangerous spikes. It also plays a significant role in treating hyperlipidemia by helping to lower unhealthy lipid levels in the body. Furthermore, the plant provides potent antioxidant activities that protect cells from oxidative stress associated with metabolic disorders. These combined properties make it a valuable natural resource for supporting long-term metabolic health.

According to a study published by "Drug design, development and therapy", Morus alba has established a functional role in inhibiting DPP-IV. This inhibition is relevant in the context of diabetes, where blocking the activity of DPP-IV can help regulate blood glucose levels. By modulating the activity of GLP-1, such inhibition helps mitigate the degradation of the hormone. Out of the eighteen plants that showed inhibition against DPP-IV through in silico, in vitro, and in vivo studies, Morus alba is one of the plants that has proven effectiveness through studies in humans. This plant is among the ten plants reported for efficacy in clinical studies.

The main health conditions this plant is used for are shown in the list below.

  • Type 2 diabetes
  • Blood glucose levels
  • Hyperglycemia
  • Lipid metabolism

What herbs are paired with Morus alba?

This plant Morus alba, commonly known as white mulberry, pairs effectively with ginger, cinnamon, and licorice to enhance its traditional medicinal properties.

When used in herbal teas, the addition of ginger helps to balance the cooling nature of the mulberry leaves while promoting better digestion. Cinnamon can be integrated to provide a warming effect that complements the plant's ability to support respiratory health. Licorice root is another frequent companion because its natural sweetness masks the subtle bitterness of the leaves and assists in soothing the throat.
