nervous breakdown:

  root, decoction, orally1

For nervous breakdown: There is no available information establishing a means of preparation and dosage other than that referred to by traditional use.

According to published and other information:

Use for nervous breakdown is classified as REC, based on the significant traditional use documented in the TRAMIL surveys, toxicity studies, scientific validation and available published scientific information.

Not for use concurrently with alcoholic beverages or drugs that are depressants of the central nervous system.

Not for use during pregnancy, during lactation or by children under 5 years old.

Should there be a notable worsening of the patient’s condition, or should the nervous breakdown last more than 5 days, seek medical attention.

Not for use for more than seven consecutive days.

TRAMIL Research4

The aqueous extract from the root (decoction) administered orally to mice reached an LD50 higher than 25 g/kg of dried root; by intraperitoneal administration, LD50 = 13.7 ± 0.2 g/kg.

The aqueous extract from the root (6.25, 12.50 and 18.75 g/kg), administered orally to mice for 30 and 60 days, did not show signs of subchronic toxicity.

There is no available information documenting the safety of medicinal use in children or in pregnant or lactating women.

TRAMIL Research2

The preliminary phytochemical screening (stem and leaves) did not indicate the presence of alkaloids.

The leaf contains diterpenes: cornutines C-L3.

TRAMIL Research4

The aqueous extract (decoction) from the root administered orally to albino mice (5 females, 5 males) of similar weight, in a logarithmic series of up to 25 g/kg dosage, caused overall depressant effects, particularly in the areas of consciousness, motor activity, motor coordination, muscular tone and, to a lesser degree, in reflexes and the autonomous nervous system.  Depression lasted 24 hours and caused marked hypothermia.
