关于榛叶提取物
Hazel is a member of the birch family of trees, Betulaceae,There are 14?18 species of hazel .Hazel can grow to a height of 10 metres, although in Scotland it is usually no more than 6 metres tall.榛树是桦木科桦树科的一员，有XNUMX到XNUMX种榛树。榛树可以长到XNUMX米，尽管在苏格兰通常不超过XNUMX米。 Typically it has a number of shoots or trunks branching out at, or just above, ground level, and this growth habit has led to some people referring to it as a bush rather than a tree, because it doesn't meet the strict definition for a tree, of having a single stem that is unbranched near the ground.通常，它在地面或地面上方分支出许多枝条或树干，这种生长习性导致一些人称其为灌木丛而不是树木，因为它不符合严格的定义。一棵树，单根茎在地面附近没有分支。
