關於榛葉提取物
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.榛樹是樺木科樺樹科的一員，有XNUMX到XNUMX種榛樹。榛樹可以長到XNUMX米，儘管在蘇格蘭通常不超過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許多枝條或樹幹，這種生長習性導致一些人稱其為灌木叢而不是樹木，因為它不符合嚴格的定義。一棵樹，單根莖在地面附近沒有分支。
