野狼毒、枳实、橘皮、半夏、麻黄、吴茱萸，都应当选用陈久存放的药材；其余药材则须选用精制新鲜的。
桃胶用桑灰汁浸泡后服用，百病痊愈；长期服用可使身体轻盈，在昏暗的夜晚如同月光照耀一般明亮；多服还可以辟谷（不食五谷）。

紫微夫人在叙述服用白术时说：观察草木中对自身迅速有益的药物，都不如白术。白术的气味能够遏制鬼津，益血生脑，驱逐恶气以致于纯真。
守护精气，保卫生命，古人称之为“山精”之草，“山姜”之精华。太上导仙铭说：“你想长生，就应当服用山精；你想轻身飞翔，就应当服用山姜。”
内篇记载：南阳文氏遭遇战乱，逃入壶山中，饥饿困顿几乎要死，有一人教他食用白术，于是就不感到饥饿，几十年后才回到家乡，容貌更加年轻，气力反而更强盛。所以白术又名“山精”。《神药经》说：“必定想要长生，就应当服用山精。”（出自《抱朴子》）
世人说服用白术忌讳吃雀和鸽，其实不是指斑鸠和鸽子，而是指蜃蛤之类的外郎刁曾长期服用白术，因为吃了蛤蜊而便血；吃了斑鸠和鸽子却安然无恙。曾经有两只麻雀争斗落入盆池中，过了一天都化为了蛤蜊，后来把死麻雀投入其中却不化。这是因为雀和鸽的气类相同。（出自《戎幕闲谈》）
刘奉林是周朝时的人，在嵩山学道四百年，三次炼制神丹都被邪物破坏，于是进入委羽山，闭气三天不呼吸。如今一千多年了，仍未成仙升天，只是服用黄连得以不死罢了，但不能役使鬼神。
松脂以质地镇定者为良，用细布袋盛装，浸入水中，用沸水煮沸，浮在水面的用篱笆罩住掠取，投入新水中久煮，煮不出来的丢弃不用。加入白茯苓末，捣碎过筛为粉末，每天取三钱匕含在口中，用温水漱口，然后像平常一样刷牙，再喝少许温水咽下，仍要漱口。这样可以坚固牙齿，润泽容颜，使胡须变黑。（出自《东坡大全集》）
四川有一位士人虐待他所使用的婢女，婢女便逃入山中，过了很久，看见野草枝叶可爱，便拔取根茎食用，味道很美。从此经常食用，久而久之便不再感到饥饿，身体轻便健壮。夜晚睡在大树下，听到草丛中有动静，以为是老虎，害怕地爬上树躲避。等到天亮下到平地，发现身体竟然凌空而去，从一个山峰的顶端像飞鸟一样掠过。几年后，他的家人砍柴时见到这个人，告诉主人让去捕捉，但未能抓到。一天在绝壁下遇到，从三面用网围住，不一会儿腾跃到山顶。主人对此感到奇异，有人说：“这个婢女怎么会有仙骨？不过是服用了灵药，吃了它罢了。”于是将酒饭五味香美的食物放置在往来的路上，观察她是否进食。果然来吃，吃完后就不能远走，被擒获。详细陈述了原委，指出所吃的草就是黄精。
Radix Saposhnikoviae (Yeloudu), Fructus Aurantii Immaturus (Zhishi), Pericarpium Citri Reticulatae (Juapi), Rhizoma Pinelliae Preparatum (Banxia), Herba Ephedrae (Mahuang), and Fructus Evodiae (Wuzhuyu) should all be selected as aged and stored for a long time; other herbs must be selected as refined and fresh.
Peach gum, soaked in ash juice from mulberry branches and taken orally, cures hundred diseases; long-term consumption makes the body light and agile, shining brightly even in dark places like the moon rising; excessive consumption can also enable grain avoidance (Bigu).
(From *Baopuzi*)
Lady Ziwei stated in her narrative on consuming Atractylodis Rhizoma (Baizhu): Observing herbs that offer rapid benefits to oneself, none surpass Baizhu. The qi of Baizhu can suppress ghostly fluids, nourish blood, generate brain essence, expel evil, and lead to purity.
Guarding essence and protecting life, ancients named it "Mountain Spirit" herb and "Mountain Ginger" essence. The Supreme Guide to Immortality states: "If you desire longevity, you should consume Mountain Spirit; if you desire lightness and flight, you should consume Mountain Ginger."
The Inner Chapters record: Wen Shi of Nanyang fled into Mount Hu during chaos, starving and exhausted near death. A person taught him to eat Baizhu, after which he felt no hunger for decades until returning home. His complexion became younger, and his strength increased. Thus, Baizhu is also called "Mountain Spirit". *Shenyao Jing* states: "To ensure longevity, one must consume Mountain Spirit." (From *Baopuzi*)
It is said in the world that consuming Baizhu forbids eating sparrows and pigeons; however, this does not refer to turtledoves but to clams/shells. Diao, an external official, consumed Baizhu for a long time and suffered bloody diarrhea after eating clams, but remained unharmed after eating turtledoves. Once, two sparrows fought and fell into a basin pool; after a day, they transformed into clams. Later, throwing dead sparrows into it did not cause transformation. This is because sparrows and pigeons share similar qi categories. (From *Rongmu Xiantan*)
Liu Fenglin was a person from the Zhou Dynasty who practiced Daoism on Mount Song for four hundred years. His three attempts at refining the Divine Elixir were ruined by evil entities. He then entered Weiyu Mountain, held his breath for three days without breathing. Over a thousand years later, he has not yet ascended to immortality, having survived only by consuming Coptidis Rhizoma (Huanglian), though he cannot command spirits.
Resina Pini (Songzhi) of stable quality is superior. It is placed in a fine cloth bag, soaked in water, and boiled with boiling water. Those floating on the surface are scooped up with a basket, thrown into new water, and boiled for a long time; those that do not release their essence are discarded. Add powder of Poria Cocos (Fuling Bai), pound and sieve into powder. Take three qian bi daily, hold in the mouth, rinse with warm water, brush teeth as usual, drink a little warm water to swallow, and continue rinsing teeth. This strengthens teeth, rejuvenates the face, and blackens beard hair. (From *Dongsuo Daquanji*)
A scholar in Sichuan abused his maid, who fled into the mountains. After a long time, she found wild grass with lovely leaves and stems, pulled up the roots, and ate them, finding them delicious. She continued eating them regularly, eventually losing the sensation of hunger and becoming light and healthy. One night, sleeping under a large tree, she heard movement in the grass, feared it was a tiger, and climbed the tree to hide. At dawn, descending to flat ground, she found herself levitating, flying from the top of one peak like a bird. Years later, her family members chopping wood saw her and told her master to capture her, but failed. One day, encountering her at the foot of a cliff, they surrounded her with nets from three sides. She suddenly leaped to the mountain top. The master was amazed. Some said, "How could this maid have immortal bones? She merely consumed spiritual medicine and ate it." They placed wine, food, and five-flavored delicacies on the path to observe if she would eat. She indeed came to eat, and after eating, could not go far, allowing her to be captured. She explained everything, pointing out that the grass she ate was Polygonati Rhizoma (Huangjing).
