交白露节，先日未时将田禾以净水泼过，次日寅时以洗白布拖展禾头露水，搅下用新瓷瓶收
贮。久留不坏，香甘止渴，治诸热燥最佳。养道家谓之无为油，服食以瓮盆置方诸于中取之。
腊月以净瓶收贮净雪筑实，密封瓶口，置于阴室中，不见日色。暑天遇烦躁热渴取饮之，甚解热毒，尤
胜凉药。凡人家不可不收也。
煮蚕茧丝汤，以瓷瓶收，密封，埋净土地中，任经数年，久而愈妙。大能治瘟疫及热病消渴
不能止者，凉饮数次即止。
霜降后，采金樱子不拘多少，以粗器微捣去毛刺净，复捣破去子，约有一斗。用水二斗煮之
一饭时，漉起清汁，又入白水煮之，又漉起，又入白水煮，三次之后，其滓淡而无味去之止。将
净汁复以细密绢滤过净，锅熬之如饴乃止，收贮瓷樽中，坐凉水内一宿，用其膏。大能固精，良
方二仙丹即此膏加入芡实粉。至于止嗽止泻，补脾补肾，非医不知。
用文蛤不拘多少，为末，每一斤用糯米粉三合和匀，用温水拌得所，捻作饼子，以黄荆叶

又法
六月间用文蛤，每五斤芽茶二两，磨细为末，不必罗，用新木桶一个，将二味入其中，用凉
水浸过一掌为度，上用木盖固之。一七月水干，面上长出白毛，用木杵捣烂，又盖住。数日后用

在白露节气到来前一天，于未时（下午13点至15点）之前，用净水喷洒田间的禾苗；次日寅时（凌晨3点至5点），用洗干净的白布拖拽并展开以收集禾苗顶端的露水，搅拌后装入新的瓷瓶中收藏保存。长期存放不会变质，气味香甜甘润，能止渴，治疗各种热燥病症效果最佳。修道之人称之为“无为油”，服食者则用瓮盆，将方诸（古代取露的器具）置于其中来采集露水。
腊月（农历十二月）用洁净的瓶子收藏积雪，压实后密封瓶口，放置在阴凉的房间中，避免阳光直射。暑天遇到烦躁、发热、口渴时饮用，能很好地解除热毒，效果胜过一般的凉性药物。凡是人家都不可不收藏。
煮蚕茧丝的汤液，用瓷瓶收藏，密封后埋入洁净的土地中，任凭经过数年，时间越久越奇妙。对于瘟疫以及热病导致的严重消渴（糖尿病症状，指多饮、多尿、多食、消瘦）无法停止的情况，有极大的治疗效果，多次凉饮即可止住。
霜降节气之后，采摘金樱子，数量不限，用粗制器皿轻微捣碎以去除毛刺并洗净，再次捣破以去掉种子，大约得一斗的量。用水二斗煮它，煮一顿饭的时间，滤起清汁，再放入清水中煮，再次滤起，又放入清水中煮，经过三次之后，药渣变淡且无味，将其丢弃停止。将过滤后的净汁再用细密的绢布过滤干净，用锅熬煮至像饴糖（麦芽糖）那样粘稠为止，收藏在瓷坛中，坐入凉水中浸泡一夜，使用其中的膏剂。此膏能极大地固摄精气，良方“二仙丹”即是在此膏中加入芡实粉制成。至于止咳止泻、补脾补肾的功效，非医生不能知晓。
使用文蛤，数量不限，研成粉末，每一斤文蛤粉用三合糯米粉混合均匀，用温水调和适中，捏成饼状，用黄荆叶包裹，三天后去掉叶片，晾一天后再覆盖起来，干燥后收藏备用。具有止咳生津的功效，作用非常迅速。制作的最佳时间是六月。
另一种方法：
六月间使用文蛤五斤和芽茶二两，磨细成粉末，不需要过筛，用一个新木桶，将这两种材料放入其中，用凉水浸泡，水面高出药材一掌宽为度，上面用木盖固定密封。到七月水干后，表面长出白毛，用木杵捣烂，再次盖住。数日后用手捻搓没有颗粒残渣才好，捏成饼状，晒干听候使用。
On the day preceding the *Bailu* (White Dew) solar term, before the *Wei* hour (13:00–15:00), sprinkle clean water over the crops in the fields. On the following day, during the *Yin* hour (03:00–05:00), drag and unfold a washed white cloth to collect the dew from the tips of the grain heads, stir it down, and store it in a new porcelain bottle for long-term preservation. It does not spoil even after long storage; its fragrance is sweet and it quenches thirst, making it excellent for treating various heat-dryness conditions. Daoist cultivators call it "Wuwei Oil" (Non-action Oil). For ingestion, practitioners place a *Fangzhu* (an ancient vessel used for collecting dew) inside an urn or basin to collect it.
In the twelfth lunar month (*Layue*), store clean snow in a pure bottle, pack it tightly, seal the bottle mouth, and place it in a cool room away from sunlight. During summer, when encountering irritability, heat, and thirst, drinking this can effectively resolve heat toxicity, surpassing the effect of ordinary cooling medicines. Every household should preserve it.
Boil the silk from silkworm cocoons, collect the decoction in a porcelain bottle, seal it tightly, and bury it in clean soil. Regardless of how many years pass, the longer it ages, the more miraculous it becomes. It is highly effective in treating epidemics and severe *Xiaoke* (Wasting-Thirst syndrome, characterized by excessive thirst and urination) caused by heat diseases that cannot be stopped. Drinking it cold several times will stop the symptoms.
After the *Shuangjiang* (Frost Descent) solar term, harvest *Jinyingzi* (Fructus Rosae Laevigatae, Chinese Medlar Fruit) without limit on quantity. Lightly crush them in a coarse vessel to remove hairs and thorns, then wash them clean. Crush them again to remove the seeds, yielding approximately one *dou* (a unit of volume). Add two *dou* of water and boil for the duration of cooking a meal. Strain out the clear juice, add fresh water, boil again, and strain. Repeat adding water and boiling until, after three times, the dregs become pale and tasteless, at which point discard the dregs. Filter the remaining clear juice through fine silk gauze until clean. Boil in a pot until it reaches the consistency of *Yitang* (maltose syrup). Store in a porcelain jar, place the jar in cool water overnight, and use the resulting paste. This paste strongly secures essence (*Jing*). The renowned formula *Erxian Dan* (Two Immortals Pill) is made by adding *Qianshi* powder (Euryales Semen, Foxnut) to this paste. As for its effects in stopping cough and diarrhea, and tonifying the Spleen and Kidney, only physicians would know.
Use *Wenge* (Venerable Clam Shell, *Cyclinae Concha*) without limit on quantity, grind into powder. For every *jin* (approx. 500g) of powder, mix with three *ge* (approx. 54ml) of glutinous rice flour. Moisten appropriately with warm water, shape into cakes, wrap with *Huangjing* leaves (*Vitex rotundifolia* leaves), leave for three days to remove the leaves, air-dry for one day, then cover and store when dry. It stops cough and generates fluids, with very rapid efficacy. The best time for preparation is the sixth lunar month.
Another method:
During the sixth lunar month, use five *jin* of *Wenge* and two *liang* (approx. 60g) of sprouted tea. Grind finely into powder; no need to sift. Place both ingredients into a new wooden bucket. Soak with cool water until the water level exceeds the material by the width of a palm. Cover tightly with a wooden lid. By the seventh lunar month, when the water has dried, white mold grows on the surface. Mash it thoroughly with a wooden pestle, then cover again. After several days, when it can be rubbed between fingers without granular residue, shape into cakes, sun-dry, and keep for use.
