烹调用油的camellia oil和镲脸用的camellia oil应该是有所不同的。在The big Carrots, 我看见pure camellia oil (镲脸)要＄14。5， 只有口红大的一管， 但是烹调用油， 几块钱就可以买一大桶了。如果有楼主贴如何用extra virgin olive oil， 和如何用camellia seed oil没有什么不同。我觉得算不上误导。

二、历史上，茶油曾经是“皇封御膳”用油，据史料记载：用小米面为原料，配以杏仁、花生米、海带丝、豆腐丁和调味品、茶油，是宫廷的御膳食谱，足可显示享用茶油是一种身份的象征。

三、茶油是一种含单不饱和脂肪酸最高的木本植物油，也是所有植物油中含量最高的，其营养价值极高，在我国历属皇家贡品，《天工开物》中明朝宋应星赞其“油味甚美”，在台湾、日本及东南亚国家被盛赞为“东方橄榄油”，为健康食用油首选。

四、以油茶为主料，由花生、芝麻、炒面经科学配方，采用传统工艺精制而成的河南武陟县“武陟油茶”是传统上贡珍品，其味香美、浓而不腻、营养丰富，已有二千多年的历史，秦时称“甘醪膏汤”，汉末称“膏汤枳壳茶”，唐代始称“油茶”，沿用至今。

五、据史料记载：楚汉之争，汉高组刘邦受伤，行至武陟，食茶油后伤愈体健，遂封为宫廷御膳。

六、唐代著名诗人李商隐食后，曾为油茶赋“芳香滋补味津津，一瓯冲出安昌春”的诗句。

七、清代雍正皇帝到武陟视察黄河险工，知县吴世碌以油茶进奉，雍正食之大喜，称赞“怀庆油茶润如酥，山珍海味难媲美”，并传旨广开油茶馆，油茶由此盛名远扬。

八、相传慈禧太後和珍妃都爱用茶花籽油来护理肌肤。

九、宋美龄每晚临睡前，例必叫特护用山茶花籽油给她面部和全身按摩一遍，肌肤红润。

十、北宋著名的文学家、政治家欧阳修因政治上的分歧被贬滁州（今安徽滁县）时，自号醉翁，专事农事，拓园广植桑、花、果树木，其中不乏油茶和牡丹，并写下了著名的《醉翁亭记》、《卖油翁》和《洛阳牡丹记》等著作。也是较早推崇家乡茶油的名流之一。

十一、元朝的刘鹗在游历期间，结交甚广，皇庆元年（1312年），任扬州儒学录，后征召掌教河南、东坡、安阳三书院，四年后返乡，辟园5亩，载油茶、桑、橘等果品以千计”，可见一代名儒对家乡茶油别有一番的青睐!

十二、现代诗人卢一夫先生的一首《咏油茶》诗云：“梨花颜色梅花香，生就清容不待妆；独具英姿霜雪里，不同桃李斗春芳。”表达了对油茶别有一番傲骨的慨叹!

十三、其它典史记载：
1 、《本草纲目》记载：“茶籽，苦寒香毒，主治喘急咳嗽，去疾垢……”
2 、《农政全书》记载：“茶油可疗痔疮、退湿热……”
3 、《纲目拾遗》记载：“茶油可润肠、清胃、解毒、杀菌……”
4 、《农息居饮食谱》记载：“茶油可润燥、清热、息风和利头目……，茶油烹调肴撰，日用皆宜，蒸熟食之，责发生光，诸油唯此最为轻清，故诸病不忌……”

日本一般用茶油作为食用油：在使用鲸鱼油和石油之前，日本把茶油用来照明、润滑工具，更主要是用来食用和作化妆用途，可见其茶油使用历史久远。更多精彩文章及讨论，请光临枫下论坛 rolia.net

Abstract
Type I collagen is the primary component of the skin dermis. Both the quantity and quality of extracellular collagen are primarily related to skin ageing. In this study, we investigated the possibility that Camellia japonica oil (CJ oil) may be introduced as an anit-wrinkle agent. As a first step to this end, human COL1A2 promoter luciferase assay was performed in human dermal fibroblast cells. CJ oil was determined to activate human COL1A2 promoter in a concentration-dependent manner. In consistency with this result, while matrix metalloproteinase (MMP)-1 activity was inhibited by CJ oil, human type I procollagen synthesis was also induced by CJ oil. These results suggest the possibility that CJ oil may be involved in the skin ageing. For the evaluation of CJ oil's safety and efficiency on human skin, human skin primary irritation test and trans-epidermal water loss (TEWL) were performed. Transepidermal water loss (TEWL) was measured before treatment then, 1 h and 2 h after treatment; the forearm site was selected to measure TEWL. Also, a human skin primary irritation test was performed on the normal skin (upper back) in 30 volunteers to see if a certain material included in CJ oil has irritation or sensitization potential. In these assays, CJ oil reduced trans-epidermal water loss (TEWL) and did not induce any adverse reactions. Therefore, based on these results, we suggest the possibility that CJ oil may be considered as possible wrinkle-reducing candidates for topical application.更多精彩文章及讨论，请光临枫下论坛 rolia.net
