Utilization and Effectiveness of Herbal Medicine in Treatment of Malaria in Osun State

Concern among health professionals has been raised by the ongoing rise in the prevalence of malaria in recent years. Herbal treatments have been deemed the most popular form of traditional medicine in Africa and a high percentage used it for malaria treatment. Poor health care services with unaffordable malaria have been a major barrier to malaria control. This study investigated the use and effectiveness of traditional medicine in treatment of malaria in Osun State, Nigeria. 15 people with malaria across the three senatorial districts of Osun State were selected, using snow balling sampling techniques. Experimental design was utilised to assess the level of knowledge on malaria. Descriptive survey was used to assess the use of traditional medicine, and true experiments to test efficacy of herbal medicine. This study found that respondents have inadequate knowledge of traditional medicine for treatment of malaria and lack adequate knowledge that anopheles mosquito cause malaria. However, use of traditional medicine is high among respondents, with most of the listed herbs achieving a significant point for mean (2.5). Majority of respondents either have malaria parasites hibernated and experience malaria relapse later or the herbal medicine used were ineffective in the first place. The effectiveness of these combined herbs is also dependent on the intensity of the malaria infection. The study concluded that traditional medicine is effective among just in a few of the respondents, who combined, prepared herbs appropriately and took it as prescribed by experienced herbs experts.

Knowledge, Perception and Utilization of Herbal Medicine in Treatment of Malaria in Southwestern Nigeria

Malaria control has been a challenge around the world for decades. In malaria endemic nations like Sub-Saharan Africa, traditional herbal medicine is the most common option for treating malaria. About 80% of the world's population relies on the use of herbal medicine to treat a variety of diseases, and the use of plant materials in the treatment of illnesses has continuously expanded. This study sought to assess the level of knowledge and attitudes towards the use of traditional medicine in the treatment of malaria in southwest Nigeria. Descriptive design and multistage sampling techniques were utilised. During the first stage, three States were chosen through a balloting process utilising random sampling methods. Four (4) sections of the questionnaire were used to collect sociodemographic data and other factors that were important to the achievement of the given objectives. The findings revealed that 31.7% of the respondents had inadequate knowledge about traditional medicine for treatment of malaria. 20.8% had positive perceptions to the common herbal medicines used in the treatment of malaria. Majority stated malaria is not a serious disease to be concerned about, and that traditional medicine is superior to modern medicine. Conclusively, the results highlighted the respondent’s lack knowledge on the consequences of traditional medicine. A strong correlation between traditional medicine uses and perception in the treatment of malaria in southwest Nigeria was also discovered. The result of the study prompted a recommendation that the public health department of the ministry of health need to intensify campaign against use of unapproved herbs for treatment of malaria.

CHEMICAL CONSTITUENTS OF DICHLOROMETHANE EXTRACT FROM THE STEM BARK OF GARCINIA FAGRAEOIDES

The Garcinia genus belonging to the Clusiaceae family (Guttiferae) has been reported to be a rich source of polyisoprenylated benzophenones, xanthones and biflavonoids with various biological activities. Garcinia fagraeoides A.Chev is an evergreen hardwood tree found only in the north provinces of Viet Nam and Guangxi province of China. Its stem bark and leaves have been used in Vietnamese traditional medicine for treatment of malaria and dermatitis diseases. In our continuing studies on chemical constituents and biological activities from the genus Garcinia, the phytochemical of Garcinia fagraeoides’s stem bark collected from Thua Thien Hue province was investigated. Repeated chromatography steps over silica gel and Sephadex LH-20 of the dichloromethane partition from the methanol extract of Garcinia fagraeoides’s stem bark led to the isolation of five compounds including one polyisoprenylated benzophenone (isogarcinol (1)), two tetraoxygenated xanthones (rubraxanthone (2), a-mangostin (3)), ferulic acid (4), and pyromeconic acid (5). Their structures were elucidated mainly by analysis of their 1D, 2D NMR spectroscopy and ESI-MS data, and by comparison with reported data. The absolute configuration of isogarcinol (1) was determined by comparison of its experimental optical rotation and NMR data with the values of its stereoisomer. This is the first reported isolation of compounds 1-5 from the stem bark of Garcinia fagraeoides.

Plants used in traditional medicine for treatment of malaria by Tetun ethnic people in West Timor Indonesia

Objective: To document the medicinal plants used for the treatment of malaria by the Tetun ethnic people in West Timor–Indonesia. Methods: The ethnobotany and anthropology methods were used in the field surveys. Ninety four informants from 29 villages of 15 sub-districts in Belu and Malaka were interviewed since April to December 2017. Medicinal plants specimen were collected from the field and identified according to taxonomic methods. Results: Ninety six medicinal plants species belong to 41 families were found to be used by the Tetun ethnic people in their traditional medicine for the treatment of malaria. These plants have been used in various formulas for drinking, massage, bath, inhalation or cataplasm. Strychnos ligustrina, Calotropis gigantea, Cleome rutidosperma, Physalis angulata, Alstonia spectabilis, Carica papaya, Melia azedarach, Alstonia scholaris, Jatropha curcas, Garuga floribunda, and Tamarindus indica were the most cited plants. Conclusions: The documented plants are valuable sources for the future development of new drugs and strategies to support malaria eliminating programs that are culturally acceptable in these areas.

Quality of Artemisinin-based Combination Therapy for malaria found in Ghanaian markets and public health implications of their use.

BackgroundGhana changed their antimalarial drug policy from monotherapies to Artemisinin-based Combination Therapies in 2004 in order to provide more efficacious medicines for treatment of malaria. The policy change can be eroded if poor quality Artemisinin-based Combination Therapies are allowed to remain on the Ghanaian market unchecked by regulatory bodies and law enforcement agencies. The presence and prevalence of substandard and counterfeit Artemisinin-based Combination Therapies need to be determined on open markets in Ghana; a review of the current policy; identifying any gaps and making recommendations on actions to be taken in addressing gaps identified are essential as the data provided and recommendations made will help in ensuring effective control of malaria in Ghana.MethodsA field survey of antimalarial drugs was conducted in the central part of Ghana. The amount of active pharmaceutical ingredient in each Artemisinin-based Combination Therapy sample identified in the survey was measured using high performance liquid chromatographic analyses. Active pharmaceutical ingredient within the range of 85–115 % was considered as standard and active pharmaceutical ingredient results out of the range were considered as substandard. All samples were screened to confirm stated active pharmaceutical ingredient presence using mass spectrometry.ResultsA total of 256 Artemisinin-based Combination Therapies were purchased from known medicine outlets, including market stalls, hospitals/clinics, pharmacies, drug stores. Artemether lumefantrine (52.5 %) and artesunate amodiaquine (43.2 %) were the predominant Artemisinin-based Combination Therapies purchased. Of the 256 Artemisinin-based Combination Therapies purchased, 254 were tested, excluding two samples of Artesunate-SP. About 35 % of Artemisinin-based Combination Therapies were found to be substandard. Nine percent of Artemisinin-based Combination Therapies purchased were past their expiry date; no counterfeit (falsified) medicine samples were detected by either high performance liquid chromatographic or mass spectrometry.ConclusionA high proportion of Artemisinin-based Combination Therapies sold in central Ghana were found to be substandard. Manufacturing of medicines that do not adhere to good manufacturing practices may have contributed to the poor quality of the Artemisinin-based Combination Therapies procured. A strict law enforcement and quality monitoring systems is recommended to ensure effective malaria case management as part of malaria control.

Tanzania has over 12,000 plant species, some of which are endemic and have potential to yield useful medicines. This study seeks to document such plants used as traditional medicines for treatment of malaria in Kagera region of northwestern Tanzania and Lindi region in south eastern Tanzania. The study also reports on the antiplasmodial activity against chloroquine-resistant Plasmodium falciparum (Dd2) strain of some of the documented plants using the parasite lactate dehydrogenase method. A total of 108 plant species, among which the families Compositae (14; 12.96%), Fabaceae (12; 11.11%), Euphorbiaceae (8; 7.41%), Melastomataceae (6; 5.56%) and Myrtaceae (4; 3.70%) were documented. Sixteen (16; 44.4%) of 36 extracts from 31 plant species that were tested inhibited malaria parasites growth by more than 50%. Bersema abyssinica stem bark extract was the most active with 86.67% inhibition rate followed by Bridelia micrantha stem bark extract with 71.87% inhibition rate. These results confirm the potential for plants used in traditional medicine to yield active antimalarial compounds. Further in vitro and in vivo screening supported by bioassay-guided isolation of active compounds from plants showing good safety margin is suggested.
