充风泪出（因受风邪而流泪）的症状表现不止一种。有的是因为肾气虚弱，不能滋养肝木（肝属木，赖肾水以生），导致肝经受风邪侵袭而虚损，因此肝风内动，迎风则流泪。对于肝经虚弱的情况，适宜服用止泪补肝散来治疗。
大致的止泪原则是：根据病情轻重选用药物，重症点眼用药；如果是热泪（伴有红肿热痛等热象的流泪），内服川芎茶调散，外用清凉散点眼；如果是肝风引起的流泪，适宜用苍术散治疗。
如果不红不痛而流泪，称为“风泪”；如果伴有肿痛、发红、干涩而流泪，称为“热泪”。
如果迎风流泪汪汪不止，冬季多发，夏季少发，擦拭后眼泪又再生，且不分四季都有此症状，这称为“冷泪”。治疗冷泪可用乳香川乌丸：取川乌1个、草乌2个（去皮）、明矾1钱、白面块1个，研成细末，用猪胆汁和丸，如黍米大小。每次取一丸，夜间卧床时放入眼角大头处，流泪即可停止；或者通过艾灸来治疗。
又有肺脏久寒的情况，眼部有大穴名为“泪堂”，泪堂与肺腑相通，这种流泪难以治愈。长期流泪会导致眼睛昏暗。血气虚弱的人，眼睛不肿不红，但呈淡紫红色，伴有干涩疼痛而流泪，这称为“虚泪”。
灸法：对于长期流冷泪的情况，可艾灸上迎香穴2个、天府穴2个、肝俞穴2个，位置在第九胸椎棘突下旁开一寸处。
止泪补肝散：治疗肝虚导致迎风流泪不止。适宜艾灸睛明穴2个（位于目内眦角稍上方凹陷处）、风池穴2个、临泣穴2个。

Chongfeng Leyu (Tearing induced by wind pathogen) presents with various symptoms. One type arises from Kidney Qi deficiency failing to nourish Liver Wood (the Liver belongs to Wood and relies on Kidney Water for generation), causing the Liver Meridian to be invaded by Wind pathogen and become deficient, thereby stirring internal Liver Wind, leading to tearing upon exposure to wind. For cases of Liver Meridian deficiency, Zhile Bubgan San (Stop Tearing and Nourish Liver Powder) is appropriate.
The general principle for stopping tearing involves using potent medications: for severe cases, apply eye drops; for "Hot Tears" (tearing accompanied by heat signs such as redness, swelling, and pain), internally administer Chuanxiong Chatiao San (Ligusticum Wallichii Tea-Regulating Powder) and externally apply Qingliang San (Cooling Powder); for tearing caused by Liver Wind, Cangzhu San (Atractylodes Macrocephala Powder) is suitable.
If tearing occurs without redness or pain, it is termed "Wind Tear"; if accompanied by swelling, pain, redness, and dryness, it is termed "Hot Tear".
If tearing flows profusely upon exposure to wind, occurring more frequently in winter and less in summer, regenerating immediately after wiping, and persisting throughout all seasons, it is termed "Cold Tear". Cold Tear can be treated with Ruxiang Chuanwu Wan (Frankincense and Aconite Pill): take one Chuanwu (Radix Aconiti Preparata), two Caowu (Radix Aconiti Kusnezoffii Preparata, peeled), 1 qian (approx. 3.7g) of Mingfan (Alumen), and one piece of white flour dough, grind into fine powder, and bind with pig bile into pills the size of millet seeds. Use one pill at bedtime, placing it in the inner canthus of the eye; tearing will cease. Alternatively, treat with moxibustion.
Another condition involves long-standing coldness of the Lung Zang. The Eye has a major acupoint named Leitang (Tear Hall), which connects to the Lung and Intestines. This type of tearing is difficult to cure. Long-term flow may cause dim vision. In individuals with weak Blood and Qi, where the eyes are neither swollen nor red but appear pale purple-red, accompanied by dryness, pain, and tearing, it is termed "Deficiency Tear".
Moxibustion Method: For chronic cold tearing, moxa-burn Shangyingxiang (Yingxiang Upper) 2 points, Tianfu (Heavenly Mansion) 2 points, and Ganshu (Liver Shu) 2 points. These are located 1 cun lateral to the spinous process of the ninth thoracic vertebra.
Zhile Bubgan San (Stop Tearing and Nourish Liver Powder): Treats continuous tearing upon wind exposure due to Liver deficiency. It is also suitable to moxa-burn Jingming (Bright Eyes) 2 points (located slightly above the inner canthus), Fengchi (Wind Pool) 2 points, and Linqi (Approaching Flow) 2 points.
