灵芝类的真菌有多种植物多糖，这些多糖有类似细菌细胞壁的多糖那样的结构，容易引起人身体内免疫细胞的反击性反应。如果在体外的细胞培养体系里加入这种真菌多糖，就会刺激免疫细胞做出反应，增强其杀肿瘤、细菌甚至病毒的能力。所以免疫学者很为此着迷。
不过，由于这些多糖引起的免疫反应过于激烈，如果注射到血液里会导致高烧休克等多种全省性危险病变，在活体内应用的危险性也很大。因此很难直接将它们注射到血液里去。也许现在有一些注射用多糖物质，用来刺激免疫活力，但估计不成气候。
口服一直是被免疫学者提倡的，北大医学院有个院长什么的就一直在鼓吹这样做。可惜，没有实验结果支持其有预防和治疗效果。吃进去就被消化了，否则还了得？
不过，蘑菇跟肉熬汤一起喝，令人精神气爽，脾胃得到调理，也算是一种治疗吧。别理它什么日本不日本产灵芝。能够买到野生蘑菇，那个香鲜是最值钱的。小时候到我哥姐插队的乡下玩，吃到的蘑菇，一直很难忘记。实在是太香鲜了。现在日本那种野生松茸，一根就有要价1万日元，合800人民币的。没听说周围的日本人买日本灵芝来吃。
我随手查到两篇文章，供你参考：

A prospective, randomized, double-blind, placebo-controlled study of the platelet and global hemostatic effects of Ganoderma lucidum (Ling-Zhi) in healthy volunteers.

Ganoderma lucidum is a Chinese herbal medicine popular with cancer patients. Previous in vitro studies suggested that Ganoderma lucidum might impair hemostasis. In this prospective, randomized double-blind study, healthy volunteers received orally Ganoderma lucidum capsules 1.5 g (n = 20) or placebo (n = 20) daily for 4 wk. We monitored subjects before drug administration and at 4 and 8 wk thereafter by routine coagulation screen, fibrinogen concentration, von Willebrand ristocetin cofactor activity, platelet function analyzer PFA-100, and thrombelastography. There were no significant between-group differences and all measurements remained within the normal range. Ganoderma lucidum ingestion over 4 wk was not associated with impairment of hemostasis. IMPLICATIONS: Ingestion of Ganoderma lucidum does not cause impairment of hemostatic function in healthy volunteers, despite earlier in vitro reports that it may cause platelet inhibition and may have other antithrombotic and fibrinolytic activity. The use of Ganoderma lucidum preoperatively is unlikely to increase the risk of surgical bleeding in otherwise healthy patients.

Lack of prevention of large intestinal cancer by VPS, an extract of Coriolus versicolor mushroom.

Cancer prevention studies were conducted with VPS, a hot water extract of the Coriolus versicolor (CV) mushroom, in female Swiss mice. The extract was administered in the diet for life to the animals. Three groups of mice received the following treatments: a). 1,2-dimethylhydrazine dihydrochloride (1,2-DMH) was administered as 10 weekly subcutaneous injections of 20 microg/g body weight, starting at 9 weeks of age; b). VPS was given at a 2% dose level starting at 7 weeks of age followed by 1,2-DMH, as described in group a; c). 1,2-DMH was administered as described in group a followed by VPS at a 2% dose level starting at 21 weeks of age. The number of animals with large intestinal tumors and the total number of these tumors were: a). 30,321; b). 29,359; and c). 28,415. These differences are not statistically significant. Because extracts of the CV mushroom are used by cancer patients as nutritional supplements in the U.S., and particularly in the Orient, the present negative result should caution its users.
