Overview
Cedrela (Spanish cedar) has many applications and medicinal benefits.
The wood is aromatic and naturally termite- and rot-resistant.
The bark of this tropical tree is employed in our herbal tincture;
it is very bitter, and is said to be febrifuge (reduce fever), vermifuge (causes the expulsion of worms or parasites from
the body) and anti-epileptic.
The resin from the bark is employed in the treatment of bronchitis.
In Traditional Medicine in Suriname, it is also used in the treatment of malaria and diabetes.
In Traditional Medicine in Brazil, a bark infusion (medicinal tea) is used as a remedy for diarrhea, fever,
anti-inflammation, vomiting, hemorrhage, and indigestion.
In Africa, the decoction of the bark is used against malaria and fever.
Constituents
Cedrela odorata is characterized chemically by the presence of tetranortriterpenoids
(limonoids). Sesquiterpene hydrocarbons: [alpha]-copaene, [delta]-cadinene, [alpha]-muurolene, [beta]-caryophyllene
and calamenene, : 6-acetoxycedrodorin, 6-deoxy-9alpha-hydroxycedrodorin, 9-alpha-hydroxycedrodorin, angolensic-acid-methyl-ester,
cedrelanol, cedrodorin, mexicanolide, gedunin, odoratol, odoratone, and photogedunine.
Pharmacology
A quantitative ethnobotanical approach to antimalarial drug discovery led to the identification
of Lansium domesticum (Meliaceae) as an important antimalarial used by Kenyah Dyak healers in Indonesian Borneo.
Triterpenoid lansiolides with antimalarial activity were isolated from the bark and shown to have activity in both
in vitro bioassays with Plasmodium falciparum, and in mice infected with P. berghei.
A survey of African and tropical American Meliaceae species led to further development of the limonoid
Gedunin from the traditionally used medicinal plants, tropical cedar, Cedrela odorata L., and Neem
(Azadirachta indica). Gedunin has significance in vitro activity but initially showed poor in vivo activity.
In vivo activity was improved by:
(1) incorporation into an easy to absorb suspension,
(2) preparation of a more stable compound, 7-methoxygedunin, and
(3) synergism with dillapiol, a cytochrome P450 3A4 inhibitor.
The results show the potential for both an antimalarial drug and phyto-medicine development from traditionally used plants.
Applications
Stomachic, tonic; for arthritis, diarrhea, dysentery, ear infections, fevers, lack of
appetite, skin ulcers, clears the lungs from mucus, malaria and diabetes.
Dosage
Tincture: 1 - 4 ml. (1 - 4 full droppers) daily.
Infusio (herbal tea): 1 - 2 cups daily.
