吉林人参
Ji-Lin Ginseng (Panax Ginseng)
和花旗参一样，吉林参也受到了世界各地的科学人员的重视。日本 Gifu 药科大学的一组研究人员指出，吉林参含有类似 NGF 的生物活性物质：
Much like its American counterpart, Chinese ginseng has also gained the attention of scientific researchers all over the world. One group of researchers at the Gifu Pharmaceutical University in Japan reported the following, suggesting that the root of Panax ginseng contains a biologically active NGF-like immunoreactive substance:
神经生长因素（NGF）是一种神经营养因素，它是人体大脑交感神经元和感觉神经元，以及前脑胆碱能神经元生存和发育所必不可少的物质。在早期老年痴呆症的研究中 NGF 受到特别的重视，因为这类病人的前脑胆碱神经在患病过程中遭到了某部份的损坏。
"Nerve Growth Factor (NGF) is a neurotrophic factor that is necessary for the survival and growth of developing sympathetic and sensory neurons, as well as basal forebrain cholinergic neurons in the brain. NGF has gained special attention in the case of Alzheimer's disease (AD) because basal forebrain cholinergic neurons are damaged selectively in AD.
“吉林参一直被用作人体恢复健康的补品，也被用作镇定剂、精神振作剂以及抗衰老、延年益寿的良方。最近有资料显示，中国人参含有的一些成份类似于 NGF 的功用，或有对 NGF 的刺激效应… 此外，人参的萃取液中也存在有细胞生长素，如表皮生长素（EGF）及类似胰岛素的物质。吉林参对中枢神经系统的一些功能也日益广为人知。
"The root of Panax ginseng C.A. Meyer (Araliaceae) has been used as a restorative drug, sedative, psychic energizer, and agent to counter senile changes and to prolong vital force. And recently, Panax ginseng has been shown to have some components with NGF-like activity or stimulatory effects on NGF action...Moreover, evidence showing the existence of peptidic cell growth factors like epidermal growth factor (EGF) and insulin-like substance in ginseng extracts has been reported, and novel action of components from Panax ginseng against the central nervous system have been recognized."
另一组日本研究人员报导：吉林参所含有的两种酸性多糖有影响免疫功能的作用。他们进一步阐述道：“在一项 ‘碳清除测试' 法中，这两种酸性多糖都会明显地增强网状内皮系统的活性，在一定的剂量范围内具有抗补体活性和抗碱性磷酸活性的作用。”
Another group of Japanese researchers reported that two acidic polysaccharides from the root of Panax ginseng manifested signs of immunological activity. They report, "Both polysaccharides showed remarkable reticuloendothelial system-potentiating activity in a carbon clearance test, pronounced anti-complementary activity and alkaline phosphatase-inducing activity in a dose dependent manner."
