Package Quantity:4 Luo Han Guo is a herbaceous perennial vine of the Cucurbitaceae (gourd) family. Native to Southern China and Northern Thailand, the plant is cultivated for its fruit, whose extract is nearly 300 times sweeter than sugar. Luo Han Guo has been used in China for centuries as a natural low-calorie sweetener and in traditional Chinese medicine to treat diabetes and obesity. After processed, it can be used as a remedy for colds and congestion of the lung. Luo Han Guo flowers in early spring. Typically all flowers are hand pollinated. The vine attains a length of 9 to 16 feet, climbing over other plants by means of tendrils which twine around anything they touch. The leaves are narrow, heart-shaped, 4 to 7 inches long. The fruit is round, 2 to 3 inches in diameter, smooth, yellow-brownish or green-brownish in color with a hard but thin skin covered by fine hairs. The inside of the fruit contains an edible pulp, which, when dried, forms a thin, light brown, brittle shell. The seeds are elongated and almost spherical. Plants can remain productive for up to 8 years.
