Indigenous knowledge has been a source of medicinal agents for thousands of years and could help to circumvent this threat. We sought to know the current indigenous knowledge used by people living in Yaounde and Douala, Cameroon to protect against covid-19. Methods : This survey was conducted with two-hundred and seventy-seven participants. A semi-structured questionnaire aiming at understanding of the practice and common interventions use by people to prevent covid-19 infection. Interviews were conducted by telephone and face to face interviews. Results : A total of thirty-nine recipes consisting in thirty-eight distinct ingredients were recorded. The recipe ingredients comprising twenty-nine medicinal plants and nine other alternatives were used for covid-19 prevention in the city of Yaounde and Douala, Cameroon. The twenty-nine medicinal...

In north-central, 22.41% of new cancer was registered for breast cancer in five years and accounted for 35.41% of all cancers in women. The limitations of orthodox drugs such as cost, accessibility, effectiveness, and side effects necessitate the search for cheap, safe and effective phytomedicine in cancer management. Thus, this paper reviewed twenty plants used traditionally for the management of breast cancer; this was with a view to presenting them for future research activities and scientific validation of their potency in cancer regimen.

The diagnostic feature that clearly distinguished Vernonia galamensis apart from lanceolate leaf shape is the possession of craspedodiomous venation. Notable characters that are of taxonomic value such as wavy anticlinal wall with polygonal cell shape differentiated V. ambigua, while straight anticlinal wall with irregular cell shape was noted in V. amygdalina and V. cinerea. All the leaves are amphistomatic and have commonly paracytic types apart from rare to occasional occurrence of other stomatal types with abnormalities. A taxonomic key based on the characters of the leaves is presented.

Semi-structured questionnaire and structured interviews were used to collect useful information. A total of 120 plant species belonging to 50 botanical families were documented. From the data, Euphorbiaceae, Solanaceae, Rutaceae, Malvaceae, Caesalpiniaceae, Poaceae and Apocynaceae (in order of decreasing number of species) were the most frequent families. Taxa such as Musa species,Vernonia amygdalina, Citrus species, Psidium guajava and Terminalia catapa were found to be the common food/medicinal plants as evidenced by their densities in the study sites. The household members cited most of the plants as food; others as medicinal and ornamentals. Miscellaneous uses include cosmetics, ceremonial and scouring. Species composition, shapes/structures as we...

Morphological features among the taxa revealed striking similarities in their habits. All the species shared common attributes in their twinning stem and leaf shape except Ipomoea aquatica which stayed apart by the possession of sagitate leaf with alternate arrangement. The petiole anatomy showed diagnostic characters that are of taxonomic value. The results showed substantial variations in the type and shape of epidermal cells from straight to polygonal and up to wavy. Preponderance of trichomes on the abaxial surface of I. triloba could be used to delimit the species. The study provides referential pharmaco-botanical information for the correct identification of the species.

This is because of the efficacy in the management of mild, chronic seemingly incurable ailments/diseases. Though the publicity is on the increase from country to country in the world, however, one cannot conclude that the information has reached all classes of people. This study therefore investigated identification, knowledge and consumption practice of herbal medicine among the hearing-impaired. The study adopted survey research design. A total of 50 students with hearing impairment were selected from different locations in Ibadan, Oyo State, Nigeria. Traditional medicinal inventory was used to collect data with reliabilities of 0.72, 0.80 and 0.67 respectively based on perception, knowledge and consumption practices. Two research questions were answered and two hypotheses tested. Result revealed wrong perception and low knowledge of traditional/alternati...

This study described the ethnobotany of the plant and evaluated the extent to which it contributes to the livelihood strategies of the Ikale and Ilaje speaking people of Ondo State, Nigeria. Methods: Interviews were conducted in the local language and questionnaires were administered to willing respondents. Photographs of tools/machines used in the production of palm oil and allied products were taken. Drawings of the tools were generated on site. Results: The plant is the principal source of palm oil. Major processing tools of palm oil include cracker, presser, digester, and boiling trough. Other products that are derived from oil palm parts are palm kernel oil, kernel meat (for livestock feed), kernel shells (for fuel), palm wine, broom, fish tra...

Information was solicited by administering questionnaires to one hundred and five (105) informants. Periodic field observations were also made. The research yielded 60 plants belonging to 37 families. The plants have characteristics such as colour, taste, habit, structure, and appellation which are suggestive of their trado-medical uses. Azadirachtha indica, Petivera alliaceae, Vernonia amygdalina, and Morinda lucida commonly known as "bitters" are used as antimalarial plants. Due to the shape of their fruits/tubers, Kigelia africana and Ipomoea batatas formed part of recipes used in the treatment of breast disorders while others such as Carica papaya and Alstonia boonei are useful as botanical galactogogues. Plants used for magical preparations are also documented. This study confirms the application of the doctrine in plant knowledge and uses. This doctrine can be applied in future bio-prospect and drug development.

Methods: Information was gathered using periodic open-ended questionnaire and personal interview. The respondents were randomly selected and consist, fifteen (15) women-herb sellers (of between 25-50, age range) who prescribed workable recipes used in the management of scalp infections, abscess, convulsion and cold shivers. The recipes documented are enumerated and served as groundbreaking preparations in infant diseases' management. Results: The survey yielded 48 plant species belonging to 31 plant families. The family Fabaceae has the highest number of species followed by Combretaceae, Meliaceae, Euphorbiaceae. The leaves and roots constituted the frequency of plant parts used; while the stem has the least frequency. The methods of preparation purposefully cited were decoction, infusion, and soap; others include steeping in cold water and cream whereas the solvent of choice was water. A particular brand of bottle water was preferable for herbal preparation. Other ingredients cited include soft traditional black soap, sulphur, Shea butter, antimony/black lead ore, and local sponge. Method of administration and dosage involves diluting extracts from infusion or decoction in higher parts of water-to be drunk, as well as for bath. Conclusion and Application of Results: The study documented indigenous knowledge of plants used in the management of infants' ailments. Results showed that herbal medicines have played and will continue to play significant roles as alternative or complementary healthcare delivery system. There is need for the sensitization of indigenous people on the conservation of plant resources especially in cases where the root (part) features in prescriptions. A regulatory measure for herbal practitioners as well as public enlightenment is recommended to help sustain and increase the awareness in herbal therapy to different audience. Again, the isolation and identification of active compounds as well as evaluative toxicity test could reveal and confirm indigenous claims by assurring safety in administration.
