BACKGROUND
Vaginal candidiasis is a common fungal infection caused by candida species, candida
albicans is the leading cause. The pathological hallmark of the disease is an acute
inflammatory condition of the vulvar and vaginal mucosa caused by fungal overgrowth in the
vagina and subsequent epithelial invasion and production of virulence factors’
Its management today with oral and topical antifungal agents is associated with increasing
development of resistance as well undesired adverse effects which cause for search of new
alternatives.
GENERAL OBJECTIVE
To develop a herbal gel from the ethanolic extract of Erythrina abyssinica for management of
vaginal candidiasis.
Specific objectives
To formulate and establish the quality of a herbal gel, to investigate the efficacy of the
prepared gel containing an ethanolic extract of Erythrina abyssinica against candida, to
determine the acute toxicity profile of a herbal gel containing ethanolic extract of Erythrina
abyssinica.
METHODS
This was an experimental study to formulate a herbal antifungal gel containing ethanolic
extract of Erythrina abyssinica against vaginal candidiasis. Erythrina abyssinica stem bark
was collected from Mityana district in Uganda and identification was done by a botanist (Dr.
Lutoti Stephen) at Makerere University. Extraction was done by maceration using ethanol
96% as a solvent. Phytochemical screening of the extract was done and a gel was formulated
using the master formulae indicated in chapter three. Quality control tests and antifungal
assay were done on the gel. The gel was also tested for safety to determine its acute toxicity
profile.

RESULTS
A powder extract was obtained from the bark of Erythrina abyssinica by maceration with
96% ethanol. The extract had antifungal activity against C. albicans with an MIC of
251mg/ml. CandiClear was successfully formulated with strength of 2%. The 1% CandiClear
had the lowest dermal irritation score and therefore the safest for topical use.
CONCLUSION
A herbal gel, CandiClear from the ethanolic bark extract of Erythrina abyssinica has activity
against C. albicans and can be considered as an alternative to conventional creams and gels
like ketoconazole cream and Nystatin pessaries. It is also safe for topical and vaginal use
