Actinidia polygama, commonly known as Silver Vine or Matatabi, is a captivating woody vine that belongs to the Actinidiaceae family. This unique plant hails from Eastern Asia, specifically Japan and China, where it has been revered for its intriguing characteristics and potential health benefits.
The leaves of Actinidia polygama are one of its most distinctive features. They are heart-shaped, green on the upper side, and adorned with a silvery-white underside. This silver hue contributes to its common name, Silver Vine. The leaves are typically 5 to 15 cm in length and have a soft, velvety texture.
The plant produces small, fragrant flowers that are either male or female. The flowers are white to pale yellow in color and grow in clusters. The fragrance of these flowers is one of the reasons Silver Vine is of interest to cats, similar to catnip.
Actinidia polygama produces small, edible fruits that resemble kiwifruit, albeit smaller in size. The fruits are round and covered with fine, short hairs. They change in color as they ripen, starting from green and turning to a pale yellow-orange hue. While humans can consume these fruits, they are more commonly enjoyed by wildlife.
Silver Vine is a climbing vine that can grow to considerable lengths. Its tendrils aid in attaching to supporting structures, making it a versatile and ornamental addition to gardens or natural landscapes.
Actinidia polygama is native to the deciduous forests of Eastern Asia. It thrives in areas with well-draining soil and prefers partial shade to full sunlight. The plant’s growth can be vigorous, especially when provided with suitable support for its climbing nature.
Actinidia polygama has cultural and traditional significance in its native regions. It has been used in various folk remedies and traditional medicine practices for its potential health benefits, including stress relief and relaxation.
Silver Vine has garnered attention for its potential to enrich the lives of pets, particularly cats, due to its catnip-like effects. However, its appeal extends to humans as well, thanks to its various medicinal properties. As with any plant, responsible harvesting and cultivation are important to ensure its long-term availability and conservation.

Nutritional Value of Actinidia polygama (Silver Vine)
1. Carbohydrates: The fruits of Actinidia polygama contain carbohydrates, primarily in the form of sugars and starches, providing a source of energy. These are present in the small, edible berries, similar to related kiwifruit species, though the fruits are less palatable and smaller in size.
The berries’ carbohydrate content supports their traditional use as a minor food source, but processing may be needed to improve taste and digestibility.
2. Fiber: Dietary fiber is found in the fruit pulp and leaves, aiding digestion and promoting gut health. Fiber helps regulate bowel movements and may contribute to overall metabolic health when consumed in herbal preparations.
As a climbing vine, the plant’s fibrous structure enhances its role in traditional diets for digestive support.
3. Protein: Trace amounts of protein are present in the leaves and fruits, supporting tissue repair and growth. While not a high-protein food, it adds to the nutritional profile in small servings used traditionally.
Protein levels are modest, aligning with its primary ornamental and medicinal uses rather than as a staple.
4. Vitamin C: The fruits are rich in vitamin C, similar to other Actinidia species, with levels contributing to immune function and antioxidant protection. This vitamin supports collagen synthesis and combats oxidative stress.
Vitamin C content makes the berries a potential source for nutritional supplements in traditional contexts.
5. Phenolic Compounds: The plant contains phenolic compounds, such as those identified in extracts, acting as antioxidants to reduce oxidative stress. These compounds support cellular health and may enhance the fruit’s overall nutritional value.
Phenolics are key to the plant’s bioactive profile, providing benefits beyond basic nutrition.
6. Flavonoids: Flavonoids, including quercetin derivatives, are present in the fruits and leaves, offering anti-inflammatory and antioxidant effects. They help protect against chronic diseases when incorporated into diets.
Flavonoids contribute to the plant’s high nutritional and therapeutic potential.
7. Minerals (Potassium): Potassium is found in the fruits, aiding electrolyte balance, nerve function, and muscle contractions. Levels are comparable to related kiwifruit, supporting hydration and cardiovascular health.
This mineral enhances the berries’ role as a hydrating and nutrient-dense food.
8. Minerals (Calcium): Trace calcium in the leaves and fruits supports bone health and muscle function. Though quantities are modest, it adds to the plant’s mineral profile for supplementary nutrition.
Calcium presence is inferred from genus studies, promoting its use in balanced diets.
9. Essential Oils: The stems and leaves contain essential oils with iridoids like nepetalactol, which have bioactive properties but minimal direct nutritional value. These compounds may aid digestion indirectly.
Essential oils are more pharmacological, contributing to the plant’s medicinal rather than caloric nutrition.
10. Alkaloids: Alkaloids in the plant provide potential health benefits but are not primary nutrients. They may influence metabolic processes, though toxicity concerns limit consumption.
Scientific Evidence and Case Studies on Actinidia polygama
1. Kim et al. (2023): This study examined the effects of Actinidia polygama ethanol extract (APEE) and water extract (APWE) on wrinkle formation in UVB-irradiated hairless mice. Both extracts significantly reduced wrinkle formation, improved skin elasticity, and inhibited matrix metalloproteinases, demonstrating anti-photoaging benefits through antioxidant mechanisms (Kim, Y. J., et al. (2023). Effect of A. polygama APEE (Actinidia polygama ethanol extract) or APWE (Actinidia polygama water extract) on wrinkle formation in UVB-irradiated hairless mice.

2. Lee et al. (2024): Researchers investigated APWE’s protective effects against UVB-induced photoaging via MAPK/AP-1 and TGFβ-Smad pathways in vitro and in vivo. The extract suppressed collagen degradation and inflammation, confirming its potential for skin health applications (Lee, J. O., et al. (2024). Actinidia polygama Water Extract (APWE) Protects Against UVB-Induced Photoaging via MAPK/AP-1 and TGFβ-Smad Pathway. Nutrients, 16(3), 389).
3. Choi et al. (2004): This study evaluated the anti-inflammatory activity of Actinidia polygama fruit extracts in animal models of inflammation. The extracts significantly reduced paw edema and pain responses, attributed to inhibition of inflammatory mediators, supporting traditional uses for arthritis and pain (Choi, B. T., et al. (2004). Anti-inflammation activity of Actinidia polygama. Journal of Ethnopharmacology, 91(1), 51-54).
4. Latocha (2017): A review highlighted the nutritional and therapeutic properties of Actinidia species, including A. polygama, noting its high antioxidant capacity from phenolics and flavonoids. Extracts showed anti-inflammatory, antiallergic, and hepatoprotective effects, with potential for immune-mediated disease prevention (Latocha, P. (2017). The Nutritional and Health Benefits of Kiwiberry (Actinidia arguta) – a Review. Plant Foods for Human Nutrition, 72(4), 429-443).
