Relevant Discussions

1. *Ben Cao Hui Yan*: “Aconite is a potent medicine that restores yang qi, dispels yin cold, expels cold phlegm, and unblocks the joints. For all diseases characterized by deficiency of true yang, rising deficient fire, difficulty swallowing, inability to eat or drink, and conditions where cold medicines only worsen the condition, Aconite is the primary medicine for the Gate of Life. It can penetrate to the very source to summon the yang, guiding the fire back to its origin, thereby extinguishing the wandering fire.In all cases of yang deficiency and extreme yin, where there are no signs of heat in the lungs or kidneys, taking it has the extraordinary power to revive the dying.”

2. *Ben Cao Zheng Yi*: “Aconite is inherently pungent, warm, and intensely hot. Its nature is to move rapidly, making it an essential medicine for unblocking the pure yang of the Twelve Meridians. Externally, it reaches the skin and hair to dispel superficial cold; internally, it reaches the Lower Jiao to warm chronic cold. Penetrating both internally and externally, it treats all cases of true cold in the Triple Burner, meridians, and all organs and viscera.”

Processing & Preparation

Harvesting & Processing

Harvested from late June to early August; the mother root, fibrous roots, and mud and sand are removed; this is commonly known as “mud-covered Aconite.”Select large, uniform mud-covered Aconite roots, wash them thoroughly, and soak them overnight in an aqueous solution of edible bile. Then add table salt and continue soaking. Remove the roots daily to sun-dry them, gradually increasing the drying time until a large amount of crystalline salt granules (salt frost) appears on the surface of the Aconite roots and they become hard; this is commonly known as “salted Aconite.”Raw Aconite is toxic; processing reduces its toxicity, making it suitable for internal use. The purpose of processing it into Salted Aconite at the place of origin is to prevent the medicine from spoiling and to facilitate storage.

Processing Methods

1.Black Smooth Slices: Take mud-covered Aconite, wash it according to size, soak it in an aqueous solution of edible gallnut for several days, then boil it together with the soaking liquid until thoroughly cooked through. Remove, rinse with water, cut lengthwise into slices approximately 0.5 cm thick, rinse again with water, and dye the slices a dark tea color using a coloring solution. Remove, steam until an oily sheen and luster appear, then oven-dry until half-dry before sun-drying or continuing to dry in the oven.

2. White Prepared Aconite Slices: Take mud-covered aconite roots of uniform size, wash them thoroughly, soak them in an aqueous solution of edible bile salt for several days, then boil them together with the soaking liquid until cooked through. Remove them, peel off the outer skin, cut them lengthwise into slices approximately 0.3 cm thick, soak and rinse them in water, remove them, steam them thoroughly, and sun-dry them.

3. Roasted Aconite Slices: Place sand in a pot and heat over high heat. Add the Aconite slices and stir-fry until they puff up and change color slightly. Remove, sift out the sand, and let cool. Roasted Aconite Slices primarily warm the kidneys and spleen and are used to treat cold pain in the chest and abdomen, as well as vomiting and diarrhea caused by deficiency-cold.

4. Lightly Salted Aconite Slices: Take salt-processed aconite, soak it in clean water, changing the water 2–3 times daily until all salt is removed. Boil it together with licorice and black beans in water until the aconite is thoroughly cooked; when cut open, it should no longer cause a numbing sensation on the tongue. Remove from heat, discard the licorice and black beans, slice thinly, and dry. For every 100 kg of salt-processed aconite, use 5 kg of licorice and 10 kg of black beans.Mildly Processed Aconite Slices excel at restoring Yang to reverse collapse, dispelling cold, and relieving pain. They are used for Yang-collapse with deficiency, cold limbs and a faint pulse, cold-induced edema, and Yang-deficiency with external pathogenic factors.

Storage Methods

Store in a well-ventilated, dry place; salted Aconite should be kept in an airtight container.

Aconitum, a plant of the genus Aconitum in the Ranunculaceae family.

Morphological Characteristics

A perennial herb, 60–150 cm tall. The tuber is obconical, 2–4 cm long and 1–1.6 cm in diameter; in cultivated varieties, the lateral roots are typically enlarged, reaching up to 5 cm in diameter, with a blackish-brown outer skin. The stem is erect, sparsely covered with short, recurved soft hairs from the middle upward. Leaves are alternate; lower stem leaves wither at flowering, while middle leaves have long petioles;petioles 1–2.5 cm long, sparsely covered with short soft hairs; leaf blades pentagonal, 6–11 cm long, 9–15 cm wide, base shallowly cordate, 3-lobed almost to the base, the central lobe broadly rhomboid, obovate-rhomboid, or rhomboid, apex acute or shortly acuminate, nearly pinnately lobed, with two pairs of secondary pinnate lobes,oblique-triangular, with 1–3 teeth, occasionally entire; lateral entire lobes unequally and deeply bifid, margins of each lobe coarsely toothed or notched, upper surface sparsely covered with short appressed hairs, lower surface usually sparsely covered with short soft hairs only along the veins, leathery or papery.Inflorescences are terminal racemes, 6–25 cm long; the rachis and pedicels are covered with short, recurved, appressed pubescence; lower bracts are 3-lobed, while upper bracts are lanceolate; pedicels are 1.5–5.5 cm long; bracteoles are borne on the middle to lower part of the pedicel;Flowers are bisexual and bilaterally symmetrical; sepals are 5, petal-like; the upper sepal is tall and helmet-shaped, 2–2.5 cm tall, with a length from the base to the beak of 1.7–2.2 cm; the lower margin is slightly concave, and the beak is inconspicuous; the lateral sepals are 1.5–2 cm long, bluish-purple, and covered with short soft hairs on the outer surface;Petals 2, each ca. 1.1 cm long. Lip ca. 6 mm long, slightly concave; spur 1–2.5 mm long, usually curled, glabrous; stamens numerous, filaments with 2 small teeth or entire, glabrous or pubescent; carpels 3–5, pubescent, rarely glabrous; capsule 1.5–1.8 cm long.Seeds are numerous, trigonal, 3–3.2 cm long, with both surfaces densely covered with transverse membranous wings. Flowering period: August–September; fruiting period: September–October.

Distribution Area

Distributed in southern Liaoning, Jiangsu, Zhejiang, Anhui, Jiangxi, Shandong, Henan, Hubei, Hunan, northern Guangdong, Guangxi, Sichuan, Guizhou, Yunnan, Shaanxi, and Gansu. It is primarily cultivated in Sichuan. It is also cultivated in Hubei, Hunan, Yunnan, Shaanxi, and other regions.

Growth Habits

It prefers a warm, humid climate, is cold-tolerant, but is sensitive to high temperatures and waterlogging. It can be cultivated in both flatland and hilly areas. It is best grown in sandy loam or purple soil that is deep, loose, fertile, and well-drained, where rice or corn has been rotated for 4–5 years or more; continuous cropping should be avoided.

Propagation Methods

Propagation is primarily through Aconite tubers.

Cultivation Techniques

Selecting varieties developed by the Sichuan Institute of Traditional Chinese Medicine—Chuanyao No. 1 (pumpkin-leaf type), Chuanyao No. 6 (loofah-leaf type), and Chuanyao No. 5 (small-flowered leaf type)—yields higher production.Early to mid-December is the optimal planting period. Dig holes spaced 16 cm apart in both rows and between plants; plant one tuber per hole. For every 10 holes, plant an additional 1–2 tubers outside the rows as replacements in case of plant loss. Immediately after planting, dig furrows and mound the soil from the furrows onto the ridges to cover the Aconite tubers with a layer approximately 6 cm thick. Approximately 8,500–10,000 Aconite tubers can be planted per mu.

Pest and Disease Control

1. White Mold: This disease is prone to occur during the hot and rainy summer months. Dig up and remove diseased plants and soil, sprinkle lime to disinfect the affected holes, and water the holes around neighboring plants with a 500-fold dilution of 50% carbendazim.

2. Downy Mildew: Thoroughly pull out diseased plants during the seedling stage, and spray the upper and lower surfaces of the leaves with a 1:1:150 Bordeaux mixture.

3. Leaf spot disease: Occurs from April to September. Spray once every 10–15 days with a 500-fold dilution of carbendazim suspension concentrate or a 1:1:150 Bordeaux mixture. For wilt disease, soak seeds in a 500-fold dilution of 40% carbendazim suspension concentrate for 3 hours before planting.

4. Powdery mildew, which affects the leaves, can be controlled by spraying the leaf surfaces with a 2,000-fold dilution of 25% triazole suspension.

5. Black velvet beetle; its larvae damage aconite.

6. Aconite delphinium aphid, occurring from May to October.

7. Black leafroller moth, occurring from April to October.

Processed Aconite Root is the name of a traditional Chinese medicine. It refers to processed preparations of Aconite Root, including processed Aconite Slices, Salted Aconite Root, Black Aconite Slices, and White Aconite Slices. It has the therapeutic effects of restoring Yang to reverse collapse, tonifying fire to assist Yang, and dispelling cold to relieve pain.It is primarily used to treat yang collapse and deficiency-collapse, cold limbs and faint pulse, deficiency of heart yang, chest bi and heart pain, deficiency-cold vomiting and diarrhea, cold pain in the epigastrium and abdomen, kidney yang deficiency, impotence and uterine cold, yin-cold edema, yang deficiency with external pathogenic factors, and cold-damp bi pain.
