马兰为菊科植物,江、浙等省常作蔬菜食用。以往认为无毒,其实大量服用会引起中毒。如猪吃了大量马兰就能引起中毒。我站近来发现马兰有同士的宁相类似的强烈中枢兴奋作用的成分。试验证明:猪吃少量无毒害作用,吃入中量即发生不同程度的中毒现象。人吃多量会彻夜不眠。 Malan as Compositae, Jiangsu, Zhejiang and other provinces often eat vegetables. In the past that non-toxic, in fact, taking a lot can cause poisoning. Such as pigs eat a lot of Malan can cause poisoning. I recently found out that there is a strong central stimulant in Malan that has similar characteristics to those of his counterpart. Tests show that: pigs eat a small amount of non-toxic effects, eating moderate levels of poisoning occurs. People eat too much will sleep all night.
