Sheet.
All varieties of Fraxinus excelsior are large trees of leaves with 7 - 15 leaflets opposing imparipinnadas of oval, with wide and jagged edges. The flowers are grouped in panicles side, lacking calyx and corolla, stamens and pistil only. The fruit is
a
Samara.

The ash is spreading across Europe and in certain regions cohabit with other species of the same gender. The identification of the species is quite difficult because of the existence of varieties and the possibility of intra - and interspecific hybridization.
Chemical composition.
The drug contains an acid Ursola and benzoquinone, abundant mannitoland tannins (hydrolysable and condensate) whose structure
has
not been studied. Also, have been described in the road:
Phenols acid derivatives and benzoic Cinnamic.
Coumarin in small quantity:
fraxósido, glucoside of fraxetol and esculósido.
Flavonoids:
rutoside.
Ascorbic
acidand iridoides.
The coumarin
was
concentrated in the crustswhere there is mannitol, syrinx and tannins.
The ash "Oxyphil" (Fraxinus
angustifolia
, oxycarpa subspecies) is little known in its composition: rutoside in the leaves, esculósido in the crust.
A
simple study by thin layer chromatography (TLC) of the two species, tends to prove that the leaves of both species have
a
very similar.
Pharmacological data.
Although tradition attributes to anti - inflammatory properties and diuretic drugs, does not appear to have been carried out experimental work to confirm these properties.
A
1989 study clearly demonstrates that changes the ash removal of
sodium
and chloride. The French Pharmacopoeia (1993) indicates that these two properties have been "confirmed by use. " Without doubt, this is
a
"modest anti - inflammatory remedy symptomatical"and
a
study in rats diuretic properties qualify as "weak".
Employment.
In Spain this plant is licensed for the treatment of gout, joint pain,
osteoarthritis
,
arthritis
. It is also used in the demonstrations painful joints,
tendinitis
and esesguinces. Facilitates the
functions
of disposal of the body (
gastrointestinal
and renal)
Facilitates
weight
loss, along with dietary measures. Analgesic and antipyretic.
The drug criomolida presents no acute toxicity (2 g / kg) or subacute (300 and 900 mg / kg / day) in rat, per os.
The drug.
The drug is presented often in the form of leaflets oval and separated spine. The leaflets,
sessile
or slightly petiolated, are lined by thin and sharp teeth, more numerous than the
lateral
veins (in

, subsp. Oxycarpa are more spaced) The microscopic examination of the powder shows some hairs secreting octocelulares in the form of
a
