I believe you're asking "What is lá sâm Ngọc Linh in English?"
The answer is Ngọc Linh ginseng. "Lá sâm" refers to the leaves of the plant, and "Ngọc Linh" specifies its origin in the Ngọc Linh mountain range of Vietnam. This ginseng is highly prized for its purported medicinal properties and is often referred to simply as Ngọc Linh ginseng, or sometimes as Vietnamese ginseng. While the leaves are part of the plant, the root is the primary part used medicinally. Therefore, "Ngọc Linh ginseng" is the most accurate and commonly used English translation.
