Core Viewpoint - The article emphasizes the dangers of consuming Cao Wu (草乌), a toxic herb traditionally used in winter dietary practices in Yunnan, highlighting the need for caution and proper knowledge regarding its use [1][2]. Group 1: Toxicity of Cao Wu - Cao Wu contains the highly toxic alkaloid aconitine, with as little as 0.2 milligrams being enough to cause poisoning, and 3-5 milligrams potentially fatal [2]. - Common cooking methods such as boiling or soaking do not eliminate its toxicity, making it unsafe for consumption without professional preparation [2]. Group 2: Prevention of Poisoning - It is crucial to use Cao Wu and related herbs only under the guidance of a qualified medical professional, avoiding self-purchase and consumption [3]. - Only processed versions of the herb should be used, as raw Cao Wu is significantly more toxic than its prepared counterparts [4]. - Caution is advised against consuming homemade herbal wines or unmarked products that may contain toxic ingredients [4]. Group 3: Emergency Response - In case of acute poisoning, there is no specific antidote for Cao Wu; symptoms such as numbness in the mouth and face, itching, and nausea require immediate medical attention [5]. - Drinking water to induce vomiting is recommended, and it is important to bring any remaining herb to the hospital for proper diagnosis and treatment [5]. Group 4: Winter Dietary Recommendations - Traditional wisdom suggests winter diets should focus on warming and nourishing foods, emphasizing the intake of natural ingredients rich in protein, vitamins, and minerals [6]. - Recommended foods include lamb, which is warming and rich in protein; white radish, which aids digestion; yam, which supports gastrointestinal health; and black sesame, which benefits skin and digestion [6].

首先注重保湿：洗澡后3-5分钟内趁皮肤微湿，涂抹含甘油、尿素或凡士林的润肤霜，每天1-2次， 干燥严重时可增加次数；洗手后及时涂护手霜；室内用加湿器维持50%-60%湿度也很关键。 其次减少刺激：适度洗澡，出汗不多时，每周2-3次即可，水温控制在37-40℃，避免搓澡，选择护 肤型沐浴露。 最后调整生活习惯：要注意休息，保证每晚7-8小时睡眠，促进皮肤修复；少刺激，饮食清淡，避 开辛辣油腻食物；贴身衣物换成纯棉或真丝材质。 这些简单的调整，能从根源上修复皮肤屏障，锁住水分，比抓挠更有效。 一是室外寒冷干燥，室内过热，让空气湿度降低，达不到皮肤健康所需的要求。 二是洗澡时水温过高、用力搓洗，再加上碱性肥皂的刺激，破坏了皮肤的保护油脂膜。 三是平时穿着的化纤衣物摩擦皮肤，食用辛辣刺激食物以及睡眠不足等因素，都让皮肤屏障雪上加 霜。 想要摆脱这种 "抓挠怪圈"，可以遵循以下的原则： 人民网北京12月17日电 （记者乔业琼）据无锡疾控微信公众号消息，冬季瘙痒症是季节性皮肤 病，专门盯着皮脂腺分布少的部位 "下手"，小腿、前臂和手部都是高发区，老年人因为皮肤老化、油 脂分泌减少更是易感人群。 冬季瘙痒症的出现，离不开 ...

贴了膘还怕冷，问题出在这 但为啥有人胖了还喊冷，瘦子反而不怕冻？关键不在"隔热层"够不够厚，而在身体"产热能力"强不 强。把人体比作房间，脂肪是墙壁厚度，新陈代谢和肌肉才是暖气——要是暖气功率不够，墙再厚，房 间早晚也会冷。 身体产热靠四个"供暖系统"：基础代谢（像小火炉，代谢高就一直产热）、肌肉活动（肌肉多，动 或不动都能产热，爱运动的人更抗冻）、战栗产热（冷到打哆嗦，肌肉快速收缩产热）、非战栗产热 （靠棕色脂肪，冷的时候烧白色脂肪和糖产热，锻炼、常接触冷能激活它）。 对比来看：肌肉多、爱运动的瘦子，"墙壁"薄但"暖气"足，不停产热就不怕冷；光贴膘不运动的 人，"墙壁"厚但"暖气"弱，热量少，就像厚被子裹着温水袋，时间长了还是凉。 人民网北京12月17日电 （记者乔业琼）据无锡疾控微信公众号消息，最近气温骤降，总听见食堂 阿姨劝年轻人多盛点肉，"冬天得多吃点长膘，不然冻得打哆嗦！"身边不少朋友也跟着贴膘，可穿上厚 衣服还是觉得冷。大家都信"脂肪像天然羽绒服"，但贴膘真能让人不怕冷吗？ 脂肪确实能保暖 脂肪不是完全没用，它就像身体的"保暖内衣"。一是能当"绝缘层"，皮下脂肪导热性差，能挡住身 体热量往外跑，护 ...
