This formula is derived from Er Chen Tang (Two-Aged Decoction) with added herbs, and is a classic formula for severe patterns of profuse phlegm-damp with obstructed qi movement. Building on the base actions of drying dampness and resolving phlegm, its composition places particular emphasis on strengthening the movement of qi to relieve stagnation and on dispelling stubborn phlegm.
Main symptoms:
Systemic and accompanying symptoms:
Step 1: Calculate the total raw herb weight of the original formula (excluding ginger)
Step 2: Convert to a 5:1 concentrated granule
Step 3: Determine the dose per administration
The original formula's directions state: "take four qian per dose (approximately 12 g raw herbs), with one and a half cups of water and ten slices of ginger, decoct down to eight-tenths, strain, and take warm." This means that one full preparation (28.5 g) is taken in several divided doses.
[Especially important: use of fresh ginger]
Fresh ginger is essential in the original formula, used to enhance the herbs' action and to counteract toxicity.
Summary of the conversion
The precise dosing regimen for ProCare Herbs Dao Dan Tang (Expectorant Decoction) granules is:
Take 2-3 times daily, dissolved in warm water, 2-3 g per dose.
[Contraindications]:
[Modern applications]: Mainly used for Ménière's disease, epilepsy, neurogenic vomiting, chronic bronchitis, frozen shoulder, and sequelae of cerebral infarction, in patterns identified as profuse phlegm-damp with obstructed qi movement. The key to its application lies in the co-presence of "phlegm" and "qi" stagnation, with phlegm being the more prominent pattern.
Summary:
The original Dao Dan Tang formula is Er Chen Tang with the addition of Tian Nan Xing and Zhi Shi. The addition of Tian Nan Xing greatly strengthens its phlegm-resolving power, making it especially effective at dispelling stubborn phlegm and wind-phlegm; the addition of Zhi Shi strengthens its ability to move qi and relieve stagnation, making it effective at breaking up the entrenched interlocking of phlegm and qi. It is therefore suitable for conditions with more severe phlegm turbidity and more pronounced qi stagnation, presenting with more serious symptoms such as dizziness, phlegm syncope, and fullness and oppression in the chest and rib-side, and is a classic formula for phlegm syncope and stubborn, congealed phlegm. ProCare Herbs granules render it convenient through modern manufacturing processes, but the conversion dosage and method of administration must be strictly followed, with particular attention to the use of fresh ginger.
本方由“二陈汤”加味化裁而来,是治疗湿痰壅盛、气机阻滞之重证的经典方剂。其配伍在燥湿化痰的基础上,着重增强行气开郁、搜涤顽痰之力。
主症:
全身及兼症:
第一步:计算原方生药总重量(不含生姜)
第二步:换算成5:1浓缩颗粒剂
第三步:确定服用剂量
原方服法为“每服四钱(约12g生药),水一盏半,姜十片,煎至八分,去滓温服”。这意味着一剂药(28.5g)是分多次服用的。
【特别重要:生姜的使用】
原方中生姜至关重要,用于增强药力并解毒。
总结与换算核心
普康本草导痰汤颗粒剂的精准服用方案为:
每日2-3次温水送服,每次2-3克。
【禁忌】:
【现代应用】: 主要用于梅尼埃病、癫痫、神经性呕吐、慢性支气管炎、肩周炎、脑梗塞后遗症等,辨证属痰湿壅盛、气机阻滞者。其应用关键在于“痰”与“气”并见,且痰证较重。
总结:
导痰汤原方是在二陈汤基础上,加天南星、枳实而成。天南星的加入,使其化痰之力大增,尤其善于涤除顽痰、风痰;枳实的加入,使其行气开郁之功更强,善于破解痰气交阻的胶着状态。因此,本方适用于痰浊更甚、气结更重,出现了眩晕、痰厥、胸胁痞满等较重症状的病证,是治疗痰厥及顽痰胶固的经典名方。普康本草颗粒剂通过现代工艺将其便捷化,但需严格遵循换算剂量与服用方法,尤其注重生姜的配伍使用。
