American Indian Use:
- Traditionally used as a diaphoretic in agues and general fevers. Reportedly cured many cases of yellow fever and smallpox.
- Rheumatism - root decoctions used externally to steam painful joints.
- Root decoctions for facilitating partruition, menstrual disorders and for 'chest difficulties' [Pedersen]
- Snake-bite antidote - root poultices applied [3,4,9]
Early use by European Americans:
- Early settlers extracted whole roots with whisky and drank it as rheumatism cure 
- Barton (1801) in Collections &c.(reprinted by Lloyds) wrote up the plant as an astringent
- Used a strong root decoction for 'putrid sore throat'.
- Also used for 'the itch'.
- Dr.Garden reported on the use of Cimicifuga racemosa in treating pulmonary TB - American Medical Recorder 1823. He actually used it on himself when afflicted by TB with positive results. He reaffirmed his belief in this remedy in 1850.
- Chapman (1825) classified Cimicifuga racemosa as an expectorant, and at this time it was widely used to treat pulmonary diseases, esp asthma & consumption.
- 1830 - introduced into US Pharmacopoeia. Remained till 1936. In NF 1936-50.
- Young (1831) described use of Cimicifuga racemosa in chorea and St.Vitus Dance.
- Howard (1832) promoted use of Cimicifuga racemosa for smallpox, a claim supported later by Dr. Norris (1872) in a paper read to the Alabama State Medical Assn. who reported families in Alabama who used Cimicifuga racemosa tea during an epidemic were absolutely free from smallpox 
- In 1848 an AMA committee analysed Cimicifuga racemosa and found it had no perceptible increase in any secretions, but "They uniformly found it to lessen the frequency and force of the pulse, to soothe pain and allay irritibility". Cimicifuga racemosa became widely recognized as a 'purely sedative agent'.
Use by Eclectics:
- King - began prescribing it in 1823, using a 'saturated tincture'.
- For 'Inflammatory rheumatism' eclectics used tincture in doses of 10-60 minims "until the patient's head is affected".
- For chorea, and for neuralgias (eg.tic doloreux), eclectics preferred the alcoholic extract, in conjunction with fluid extract of Scullcap.
- Promoted its use as a uterine agent and parturient, using it as a substitute for ergot. Especially useful for sub-involution of uterus.
- King warned of occasional reactions - some patients reported symptoms closely resembling delirium tremens after only 2/3 drops of tincture.
- Recommended fluid extract for prophylactic & remedy for smallpox.
- Febrile diseases esp. children, promotes diaphoresis.
- Acute conjunctivitis - 1 fl.drachm tinc.
- Cimicifugin - 'resin':
First chemical analysis of CR identified an amorphous resinous precipitate, which became known as macrotyn or cimicifugin. This 'resin' was prepared by King in 1835, who found it to have a less narcotic effect than the galenical preps, and to be esp. useful in female reproductive conditions [see p.287].
The 'resin' was popular amongst Eclectic practioners who were philisohically attracted to this kind of non-galenical preps. However, despite several attempts no crystals could be obtained from the precipate, only an amorphous mixture partially soluable in several menstruums. Finally J.U.Lloyd asked Prof.V.Coblentz from the Cincinatti College of Pharmacy to obtain crystals from the pure precipitate.
Conclusions see p.269 - no crystalline substance was obtained.
- Culbreth claims there are 2 resins, one soluble in alcohol and ether, the other soluble in alcohol only. The 2 are obtained as a mixture by exhausting powdered drug with alcohol, precipitating with water, and drying the precipitate to produce a yellowish-brown hygroscopic powder 
Use by Physio-meds.
- Preferred syrup preparations to fluid extract or 'resinoid' as these were less likely to cause headaches/dizziness
- Used Cimicifuga racemosa as base for alterative preps, also as tonics/antispasmodics.
- Soothes and stimulates nerves
- Used in whooping cough, asthma, hysterical convulsions, chorea : equal parts of:
- Used in bronchial congestion/inflammation: equal parts of:
- Aralia racemosa

Long history of use by Australian Herbalists. A major constituent of the Viburnum -compound used in dysmennorhoea, fibroids, and ovarian cysts. This formula used by Paul Wheeler:
