[Chi Jian (Red Arrow)] Pungent in flavor, neutral in nature. It primarily treats cough with rebellious Qi (cough and asthma), tonifies Lung Qi, unblocks the mouth and nose, strengthens willpower and intent, promotes courage and boldness, and calms the Po (Hun and Po: the corporeal soul). Long-term consumption lightens the body, prevents aging, and extends life to that of an immortal. Also known as Yu Zhi (Jade Lingzhi). Grows on Mount Hua.

[Xuan Zhi (Black Lingzhi)] Salty in flavor, neutral in nature. It primarily treats strangury (difficulty or obstruction in urination), benefits the water passages, tonifies Kidney Qi, unblocks the nine orifices, and enhances hearing and vision for clarity. Long-term consumption lightens the body, prevents aging, and extends life to that of an immortal. Also known as Xuan Zhi. Grows on Mount Heng.
[Note] Regarding the Five Lingzhi, the Classics state: they all grow in five colors upon the Five Sacred Mountains. The Lingzhi offered by various regions may not necessarily be white from Mount Hua, nor black exclusively from Mount Heng. Moreover, Lingzhi are mostly yellow or white; black and green ones are rare. However, Zi Zhi (Purple Lingzhi) is the most common but does not belong to the category of the Five Lingzhi. Since Lingzhi is inherently difficult to obtain, even if one or two are acquired, how can they be consumed continuously over a long period?

[Mu Zhi (Wooden Lingzhi)] Sweet in flavor, warm in nature. It primarily treats deafness, benefits the joints, preserves the Spirit (Shen), tonifies Essence and Qi, strengthens bones and sinews, and improves complexion. Long-term consumption lightens the body, prevents aging, and extends life to that of an immortal. Also known as Mu Zhi. Grows in the valleys of Gaoxia.
All six types of Lingzhi are non-toxic. They are harvested in June and August.
Dioscoreae Rhizoma (Shuyu) acts as its guiding herb. It yields good results when combined with human hair. When used together with Cannabis Fructus (Maziren), Cucumis Melo Semen Album (Baiguazi), and Cinnamomi Ramulus (Mugui), it is more beneficial to humans. It is incompatible with Trichosanthes Radix (Hengshan) and fears Indigo Naturalis (Bianqing) and Artemisiae Capillaris Herba (Yinchenhao). Researching administrative divisions, there is no place named "Gaoxia," so it is likely a mountain name.
These six Lingzhi are all classified as immortal herbs, rarely seen in secular society, with many varieties differing in shape and color, all recorded in *Zhi Cao* (Treatise on Lingzhi). This refers to those growing on rotting tree stumps, resembling wood, named Zi Zhi (Purple Lingzhi). It is said to treat only hemorrhoids and is not suitable for compounding into various tonic pills. Whenever Lingzhi is obtained, it should be eaten directly without specific dosage regulations; therefore, no administration methods are recorded.

[Gui Du You / Chi Jian] Pungent in flavor, warm in nature. It primarily kills demonic essences, dispels gu poison and evil qi, resolves carbuncles and swellings, alleviates upper limb fullness and hernia, and stops lower body bleeding. Long-term consumption boosts Qi and strength, promotes genital development and robustness, and lightens the body.
Also known as Gui Du You (Ghost Supervisor). Grows in Chencang, Chuangu, Yongzhou, and Mount Tai/Mount Shaoshi. The roots are harvested in March, April, and August, then dried.
Chencang belongs to Fufeng Commandery, Yongzhou Province. Research indicates this herb also belongs to the Lingzhi category. It is described as having a stem red like an arrow shaft, with leaves at the tip. The root resembles a human foot or taro, accompanied by twelve smaller offshoots acting as guards. It remains still when there is wind and sways spontaneously when there is none. Thus, it is not commonly seen in secular times. Furthermore, Xu Changqing (Cynanchum paniculatum) is also called Gui Du You. There is also Gui Jian (Arrow Ghost), which has feather-like structures on its stem. Although their therapeutic effects are similar, their benefits to the human body differ significantly. It is doubtful that either is this Chi Jian.
[Note] This type of Lingzhi has a stem resembling an arrow shaft, reddish in color. Flowers and leaves are at the tip, looking like an arrow with feathers from a distance. The juice of the root skin and flesh is similar to Asparagi Radix (Tiandong), but lacks the central vascular bundle. About five to six cun away from the root, there are over ten offshoots guarding it, resembling taro. The fruit resembles Meliae Semen (Kulianzi), with a nut having five or six ridges, and the inner meat resembling flour, which withers upon sun-drying. The root can be eaten raw immediately upon harvesting; there is no method for consuming it dried.
