Lavandula stoechas L. (Lamiaceae) is a medicinal plant of traditional Unani, Iranian and Tunisian systems of medicine. It has a unique attribute to expel out and remove all impurities and obstructions and reinvigorate the brain power, honored as broom of brain in classical Unani literatures. To establish clear identification between L. stoechas (LS) and L. officinalis (LO) standard operating parameters, TLC fingerprinting and physicochemical and histo-anatomical studies were done. LS exhibited significantly higher physical values for their standardization and quality parameters with respect to LO. Histoanatomical disquisition and chemo-microscopic studies of the drug revealed that presence of substantial and marked diagnostic feature to LS having large bract, brown colored flexible peduncle, presence of exorbitant number of uniseriate and multi seriate covering and uniseriate glandular trichomes leading to soft stem and peduncle. It has distinguished and well-developed phloem, centrally filled with parenchymatous cells, with camphoric stench along with bitter in taste while LO has lesser hairs, hard stem and peduncle, greenish color, presence of centrally hollow pith, indiscriminate bract, and flowers are without stalks with pleasant aroma. Seeds of LS are yellowish brown, frivolous weight and very small in size while LO have blackish seeds and are comparatively larger in size and weight.

模糊的传统和神奇草药 Lavandula stoechas L. 与 Lavandula officinalis Chaix 的比较物理化学和组织解剖学研究。

Lavandula stoechas L.（唇形科）是传统尤纳尼、伊朗和突尼斯医学系统的药用植物。它具有独特的祛除杂垢、振奋脑力的功效，在经典尤纳尼文献中被誉为大脑的扫帚。为了在 L. stoechas (LS) 和 L. officinalis (LO) 标准操作参数之间建立明确的识别，进行了 TLC 指纹识别以及物理化学和组织解剖学研究。LS 的标准化和质量参数相对于 LO 表现出显着更高的物理值。该药物的组织解剖学研究和化学显微研究表明，对具有大苞片、棕色柔性花梗的 LS 存在大量且显着的诊断特征，存在大量单列和多列覆盖物和单列腺毛，导致软茎和花序梗。韧皮部显着发达，中央充满薄壁细胞，有樟脑臭，味苦；LO 毛少，茎硬，色绿，髓心中空，苞片乱，花无。具有宜人香气的茎。LS的种子黄褐色，重量轻，体积很小，而LO的种子呈黑色，体积和重量相对较大。茎和花序梗硬，颜色绿，有中央空心髓，苞片无差别，花无梗，香气宜人。LS的种子黄褐色，重量轻，体积很小，而LO的种子呈黑色，体积和重量相对较大。茎和花序梗硬，颜色绿，有中央空心髓，苞片无差别，花无梗，香气宜人。LS的种子黄褐色，重量轻，体积很小，而LO的种子呈黑色，体积和重量相对较大。
