Scientific name:<\/strong> Sarcandra glabra<\/em> (Thunb.) Nakai
Family:<\/strong> Chloranthaceae<\/p>\n

Morphological Characteristics<\/h3>\n

Sarcandra glabra<\/em> is a small shrub, typically 1\u20132 meters in height, with smooth stems, swollen nodes, and round, hairless branches. Leaves are opposite, with oblong or lanceolate blades, 7\u201318 cm long and 2\u20137 cm wide, featuring 5\u20137 pairs of lateral veins. Petioles are short, around 5\u20138 mm. Leaf margins are serrated with sharp teeth. The plant flowers from May and continues blooming until November. Fruits begin to ripen at the end of August and remain on the plant until February of the following year. Inflorescences are compound spikes at the shoot tips with short branches. Flowers are small, white, sessile, and have a single stamen. The ovary is ovate and lacks a style. The fruit is small, nearly round (4×6 mm), fleshy, and brick red in color. Flowering season is from June to July, and fruiting occurs from August to September.<\/p>\n

Distribution<\/h3>\n

Sarcandra glabra<\/em> grows best in areas with deep, well-aerated, humus-rich soils, low in stones, high water retention capacity but good drainage, and consistent moisture throughout the growing period. It is distributed in countries such as China, Korea, Japan, India, Vietnam, and Malaysia. In Vietnam, it naturally occurs on rocky mountains, forest edges, and moist hillsides in areas like H\u00e0 Giang, Cao B\u1eb1ng, L\u1ea1ng S\u01a1n, H\u00f2a B\u00ecnh, Kon Tum, and L\u00e2m \u0110\u1ed3ng.<\/p>\n

Medicinal Properties<\/h3>\n

The plant contains three bioactive compounds: Chloranoside A, tertorigenin 7-glucoside, and 1\u03b2;3\u03b2-Dihydroxylup-20(29)-ene, which are effective in treating joint disorders such as rheumatism, joint pain, and digestive diseases. Powdered leaves exhibit antioxidant activity in the DPPH system and are thus used in anti-inflammatory and anti-cancer therapies.<\/p>\n

In traditional medicine, Sarcandra glabra<\/em> is slightly warm, bitter and pungent in taste, and is used to activate blood circulation, relieve pain, expel wind-dampness, reduce inflammation, and detoxify. The roots are soaked in alcohol to relieve chest pain. Leaves are decocted to treat tuberculosis, applied externally for snake bites, or used as herbal alcohol for massaging wounds, boils, rheumatism, and bone\/joint pain.<\/p>\n

Propagation Methods<\/h3>\n

Sarcandra glabra<\/em> can be propagated via stem cuttings or tissue culture.<\/p>\n

Seedling Standards:<\/strong><\/p>\n

    \n
  • \n

    From stem cuttings:<\/strong><\/p>\n

      \n
    • \n

      Seedlings should be 15\u201320 cm tall with 5\u20136 leaves.<\/p>\n<\/li>\n

    • \n

      They must exhibit good vigor, healthy root systems, and be disease-free, with lush green foliage.<\/p>\n<\/li>\n

    • \n

      Age: 3 months from propagation to transplant.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

    • \n

      From tissue culture:<\/strong><\/p>\n

        \n
      • \n

        Same standards as above.<\/p>\n<\/li>\n

      • \n

        Tissue-cultured seedlings are genetically uniform, retain mother plant traits, and have strong disease resistance but are more expensive.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

        Planting Season<\/h3>\n

        Optimal planting time is from March to April annually.<\/p>\n

        Soil Preparation and Planting Technique<\/h3>\n

        The soil must be thoroughly plowed, weeded without herbicides, and sun-dried to loosen and eliminate pest residues. Plowing depth: 20\u201330 cm. During soil preparation, apply a basal fertilizer mix of well-decomposed manure. Beds should be raised (35\u201340 cm high, 120 cm wide) with good drainage and no waterlogging.<\/p>\n

        Planting Density and Spacing<\/h3>\n
          \n
        • \n

          Spacing:<\/strong> 1.0 x 1.0 m<\/p>\n<\/li>\n

        • \n

          Density:<\/strong> 10,000 plants\/ha (standard soil); 5,000 plants\/ha (fertile soil)<\/p>\n<\/li>\n<\/ul>\n

          Fertilization<\/h3>\n
            \n
          • \n

            Basal application:<\/strong> At soil preparation, apply 5,000 kg of well-rotted manure + 150 kg of organic biofertilizer, mixed into planting holes and lightly covered with soil to avoid root burn.<\/p>\n<\/li>\n

          • \n

            Top dressing:<\/strong> Divided into 3 applications annually:<\/p>\n

              \n
            • \n

              1st application:<\/strong> 2\u20133 months after planting: 100 kg of organic biofertilizer<\/p>\n<\/li>\n

            • \n

              2nd application:<\/strong> Peak growth stage (July\u2013August): 5,000 kg manure + 150 kg organic biofertilizer<\/p>\n<\/li>\n

            • \n

              3rd application:<\/strong> Final boost (November\u2013December): 100 kg organic biofertilizer<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

              Planting and Care Techniques<\/h3>\n
                \n
              • \n

                Planting:<\/strong> Dig holes in rows, add basal fertilizers, cover with a layer of soil, place seedlings beside the fertilizer (not directly on it), and press soil firmly around the base.<\/p>\n<\/li>\n

              • \n

                Weeding and Soil Loosening:<\/strong> Regularly weed, especially during wet seasons. Loosen soil and mound bases 2\u20133 times annually to enhance aeration.<\/p>\n<\/li>\n

              • \n

                Watering:<\/strong> Water immediately after planting. For the first 30 days, irrigate daily to maintain 70\u201380% soil moisture for rooting and recovery. Continue soil moisture management throughout the growing period. Always irrigate after fertilization for nutrient absorption. Use clean surface water only.<\/p>\n<\/li>\n

              • \n

                Drainage:<\/strong> The plant is moisture-loving but intolerant of waterlogging. Raised beds and immediate drainage during flooding are essential, particularly for young plants.<\/p>\n<\/li>\n

              • \n

                Gap Filling:<\/strong> Replace dead or weak seedlings within 1\u20132 months to ensure uniform stand.<\/p>\n<\/li>\n

              • \n

                Weeding frequency:<\/strong> Once a month for the first two months; then reduce frequency. Combine with fertilizer application and soil mounding.<\/p>\n<\/li>\n<\/ul>\n

                Pest and Disease Management<\/h3>\n

                Although generally hardy, regular monitoring is essential. Maintain field hygiene, remove diseased or old leaves and crop residues, and destroy them. Use botanical pesticides if pests are detected. Employ Integrated Pest Management (IPM) to reduce chemical pesticide use\u2014prohibited substances must not be used.<\/p>\n

                Harvest and Post-Harvest Handling<\/h3>\n
                  \n
