木芝，是松树的枝干油脂渗入地下，经过千年转化为茯苓，再经万年，其上方生长出一种小树，名为“木威喜芝”。夜晚观察可见其发光，手持感觉非常光滑，燃烧时不会起火，佩戴它可以辟除兵灾。用这种芝草系住一只鸡，与其他十二只鸡关在同一个笼子里，人退后十二步，射出十二支箭，其他鸡都会受伤，而系着威喜芝的鸡却毫发无损。从生门采集它，在六甲日的阴处晾干一百天，研成粉末，每次服用一方寸匕，每天服三次，吃完一枚（指灵芝实体或特定计量单位），据说可延寿三千岁。
神仙饵松实丹：七月采集松子（松实），过时就会掉落，难以采摘。去掉木质外皮，捣碎如膏状，每次服用如鸡蛋大小，每天服三次。如果服用满一百天，身体会变得轻盈；三百天后，每天能行走五百里，可以断绝五谷饮食；长期服用可以飞升成仙。口渴时喝水即可，也可以将炼过的松脂混合服用。
七月七日采集松子，过时就会掉落，不能再使用。服用方寸匕大小的量，每天三到四次。另一种说法是服用三合，一百天后身体轻盈，三百天后每天行走五百里，断绝五谷饮食，长期服用可飞升成仙。口渴时喝水，也可以和松脂一起服用。如果制成梧桐子大小的药丸，每次服用十丸。
松脂以真定府出产的质量最好。用细布袋装好，或者用百沸清水煮，浮在水面上的为佳品，用新的竹篱捞取投入新水中。久煮仍沉底不出的都要丢弃不用。加入生的白茯苓末（不经过炮制处理），只需刮去外皮，捣碎过筛成细末拌匀，每天早上服用三钱匕，含在口中，用少量温水漱口，再用松脂像平常一样刷牙，刷完后用少量温水吞下。之后照常漱口，这种方法能极大地坚固牙齿、驻留容颜、使胡须变黑。
将百炼松脂过筛后用蜂蜜调和，放入内桶中，不要让通风。每天服用如象棋棋子大小的一块（博棋长二寸，宽一寸），每天三次，逐渐每月增加剂量。服用一斤可以不饥饿并延年益寿。也可以用醇酒和白蜜调成饴糖状，每天服用一两至半斤。凡是采集松脂，老松树皮上自然聚集的松脂是最好的。树根下有折断处，不见日月的地方得到的称为“阴脂”，效果更好。只有衡山向东五百里的地方，巨大的松树都有三四十围粗，才多产松脂。又一种方法：五月在大松树的向阳面刻口，使汁液向下流，二十四株树，每株可得半升。也可以煮老节根处，有脂液流出即可使用。《仙经》说：常在三月进入衡山的背阴处，采集不见日月的松脂，炼制后服用。即使不多，只要坚持服用，一百天后能抵御寒暑，二百天后五脏得到补益。服用五年，就能见到西王母。《仙经》又说：诸石所生的三百六十五座山中，那些可以食用的山谷里，生长的都是埋在土中的松脂罢了。那个山谷正对着衡山岭向东四百八十里，就在横捷山位于横岭东北方向。走过它的南边，进入山谷五十里，到达洞穴尽头，有一座石头城叫鹤城。那里有大石头四十多丈高，秋天时像白色的松树，松下两丈处有小洞穴。向东进入山中，有红色的丹砂石可以吃。其南方背阴处有大松树，直径三十多围，有三十多株，不见日月，都可以采集服用。服用松脂的方法，如果想断绝五谷饮食，服用三两，肚子饿时再吃，吃到饱为止，最多可达一斤。不断绝五谷饮食的人，每次服用一两，一定要先吃药，等药效过了再吃食物，否则吃了会不安稳并呕吐。长期服用可以延年益寿，百病消除。
又一个方子：松脂十斤，松子三斤，柏子三斤，菊花五斤，将这四味药过筛后用蜂蜜调和服用。制成梧桐子大小的药丸，每次三十丸，分三次服用。一百天以上不再感到饥饿，服用一年，百岁老人也能恢复如三四十岁的年轻人，长期服用可以不死。
又一个方子：在夏至日采集松脂，每天吃一升，不吃其他东西，想喝水就喝。让人长期服用，可以终身不老。在河南汝州的山中背阴处砍断松树，放在容器中蒸煮，膏脂自然流出，炼制去除苦气，与白蜜混合食用，每天一升，两个月后改为弹丸大小服用，口渴时喝水，让人不老，采集没有固定时间。
又一个方子：松脂五斤，羊脂三斤，先将这两味药炼制松脂使其融化，纳入羊脂，每天服用如象棋棋子大小的一块，不感到饥饿，长期服用可成神仙。
又一个方子：白松脂七斤，经过三次炼制的白蜡五斤，白蜜三斤，茯苓粉三斤，将上面四味药合在一起蒸一个斗的时间（注：原文“一石斗顷”疑为时间或量的误写，此处依语境理解为加工过程），制成梧桐子大小的药丸，每次十丸。肚子饿时每天吃一丸，不能吃任何食物，只能喝一次酒，需在一合酒的斋戒状态下，咀嚼五香药材，用水煮开去渣，将药物投入沸水中。如果想要招致神女，取茅草根，处理后取汁液调和，蒸熟后服用，神女就会到来。
Mu Zhi (Wood Ganoderma) is formed when the resin from pine branches seeps into the ground. After a thousand years, it transforms into Poria Cocos (Fuling). After ten thousand years, small trees grow on its upper surface, named "Mu Weixi Zhi" (Wood Weixi Mushroom). It glows at night, feels very smooth to the touch, does not burn when ignited, and wearing it can ward off military disasters. If you tie a chicken with this mushroom and place it in a cage with twelve other chickens, stand twelve steps away, and shoot twelve arrows, the other chickens will be injured, but the chicken tied with Weixi Zhi will remain unharmed. Collect it from the "Sheng Men" (Life Gate), dry it in the shade during the Six Jia days for one hundred days, grind it into powder, and take one Fang Cun Bi (a square-inch measure) each time, three times a day. Consuming one unit is said to extend life by three thousand years.
Shen Xian Er Song Shi Dan (Immortal Pine Seed Pill): Collect pine seeds (Song Shi) in July; if missed, they fall and are difficult to gather. Remove the woody skin, pound them into a paste, and take an amount the size of a chicken egg each time, three times a day. After taking it for one hundred days, the body becomes light. After three hundred days, one can walk five hundred li per day and practice Gu Yu (grain avoidance). Long-term use leads to ascending to immortality. Drink water when thirsty, or mix with refined pine resin.
Collect pine nuts on the seventh day of the seventh lunar month; if missed, they fall and cannot be used. Take one Fang Cun Bi, three to four times a day. Another method says take San He (three he), and after one hundred days the body becomes light, and after three hundred days one walks five hundred li daily, practicing Gu Yu, leading to ascension with long-term use. Drink water when thirsty, or take with pine resin. If made into pills the size of Chinese parasol tree seeds, take ten pills each time.
Pine resin (Song Zhi) from Zhending is considered the best. Place it in a fine cloth bag or boil it in boiling clear water; those that float on the surface are selected, scooped up with a new bamboo sieve, and thrown into fresh water. Discard any that do not float after prolonged boiling. Add raw Bai Fu Ling (White Poria) powder (unprocessed), simply scrape off the skin, pound and sieve into a fine powder, mix well, and take three Qian Bi every morning. Hold in the mouth, rinse with a little warm water, then brush teeth with pine resin as usual, and swallow with a little warm water after brushing. Rinse as usual. This method greatly strengthens teeth, preserves youthfulness, and darkens beard hair.
Sift refined pine resin and mix with honey, store in an inner barrel, avoiding ventilation. Take one piece the size of a chess piece (Bo Qi, 2 cun long, 1 cun square) daily, three times a day, gradually increasing monthly. Taking one jin prevents hunger and extends life. Alternatively, mix with strong wine and white honey to form a syrup, taking one to half a jin daily. For collecting pine resin, the natural accumulation on old pine bark is the finest. The resin found under broken roots where sunlight does not reach is called Yin Zhi (Yin Resin) and is even better. Only east of Mount Heng, where large pines are thirty to forty zhou in circumference, is there abundant resin. Another method: In May, incise the sunny side of large pines so the resin flows downward; twenty-four trees yield half sheng each. Also, boiling old joint roots yields usable resin. The *Xian Jing* (Immortal Classic) states: Enter the shady side of Mount Heng in March to collect pine resin unseen by sunlight, refine and consume it. Even in small amounts, consistent use allows enduring cold and heat after one hundred days, and nourishing the five Zang organs after two hundred days. Five years of use brings a vision of Xi Wang Mu (Queen Mother of the West). The *Xian Jing* also states: Among the 365 mountains born of stones, valleys filled with edible substances contain only pine resin buried in soil. This valley lies directly east of Mount Heng ridge, 480 li away, specifically northeast of Heng Ling. Passing south, enter the valley for fifty li to the cave's end, where a stone city named He (Crane) exists. There are large stones over forty zhang high, resembling white pines in autumn, with small caves two zhang below the pines. Entering eastward, red cinnabar stones are edible. In the southern shady areas, there are over thirty large pines, thirty-plus zhou in circumference, unseen by sunlight, all suitable for collection. To consume pine resin, if practicing Gu Yu, take three liang; if hungry, eat more until full, up to one jin. Without Gu Yu, take one liang, always before eating, waiting for the medicinal effect to dissipate before consuming food; otherwise, discomfort and vomiting may occur. Long-term use extends life and eliminates diseases.
Another prescription: Ten jin of Song Zhi (Pine Resin), three jin of Song Shi (Pine Seeds), three jin of Bai Shi (Cupressus Seeds), and five jin of Ju Hua (Chrysanthemum). Sift these four ingredients, mix with honey, and take. Make pills the size of tung seeds, thirty pills per dose, divided into three servings. After more than one hundred days, hunger ceases. One year of use restores centenarians to the vigor of thirty- or forty-year-olds; long-term use prevents death.
Another prescription: Collect Song Zhi (Pine Resin) on the Summer Solstice, consume one sheng daily, abstaining from other foods, drinking water as desired. Long-term use ensures lifelong youth. In Henan Ruzhou mountains, cut pines in shady areas, place in vessels, steam, and collect flowing ointment. Refine to remove bitter odor, mix with white honey, consume one sheng daily. After two months, change to pill size of a bullet, drink water when thirsty, prevents aging, collection time is flexible.
Another prescription: Five jin of Song Zhi (Pine Resin) and three jin of Yang Zhi (Sheep Fat). First refine Song Zhi until melted, add Yang Zhi. Take one Bo Qi-sized piece daily, prevents hunger, long-term use leads to immortality.
Another prescription: Seven jin of Bai Song Zhi (White Pine Resin), five jin of Bai La (Beeswax) refined three times, three jin of Bai Mi (White Honey), and three jin of Fu Ling Fen (Poria Powder). Steam these four ingredients together for a duration equivalent to emptying a stone-dou measure. Make pills the size of tung seeds, take ten pills. When hungry, take one pill daily, abstain from all food, allow only one round of wine consumption. Observe fasting rules, chew Wu Xiang (Five Spices), boil in water for one boil, strain, and drop medicine into the boiling water. To summon Shen Nv (Divine Maiden), extract juice from Mao Gen (Imperata Rhizome), mix with it, steam and consume; the Divine Maiden will arrive.
