For ages, medicinal plants play a significant role in the effective, affordable, and safe healthcare system. Medicinal plants continue to play an important role in Nigeria's healthcare system, which serves more than 70% of the country's population. For pharmaceutical exploration and conservation, it is important to document the use of medicinal plants in a specific region across time. The study's goal was to find out which plants were used to treat typhoid illness in Kaduna state. The in-depth interview guide was utilized in conjunction with an expert method and non-random probability sampling. The study discovered and recorded 31 plant species from 25 families that are used by Kaduna residents to cure typhoid diseases. Plants with a 0.45 value of relative frequency citation were documented. The highest relative frequency of citation (0.9) and fidelity level (90%) are found in Garcinia mangostana, Senna alata, Moringa oleifera, and Hibiscus sabdariffa, respectively. In Nigeria, traditional medicinal knowledge is guarded by  elderly people. The study discovered plant species that could be used as a potential source of anti typhoid in Nigeria.

Mosquito control has become more difficult due to the unsystematic use of synthetic chemical insecticides which have inauspicious effect on the environment. Botanical phyto-chemicals with mosquitocidal potential are now recognized as potent alternative insecticides to replace synthetic insecticides in mosquito control programs due to their excellent larvacidal activities. The present study assessed the influence of A. sativum (garlic), Z. officinale (ginger) and S. aromatic (clove) extracts against Aedes mosquitoes. Larvacidal activities of three indigenous plant extracts were studied in the range 5.0 to 30.0mg/l in the laboratory bioassay against fourth instar larvae of Aedes sp. The mortality were subjected to probit analysis to determine the lethal concentration (LC50) to kill 50 percent of treated larvae of Aedes sp. Data obtained were analyzed by Comparing experimental groups and control groups with significance level established at p<0.05. All plants tasted showed effects after 24hrs of exposure at different concentration (mg/l). However the highest mortality was found in A. Sativum (garlic) and Z. officinale (ginger) against larvae of Aedes mosquitoes with LC50 = 42.50% (2.685) and LC50 = 30.01% (4.461) mg/l, while S. aromatic(clove) was found to have lowest mortality at LC50 = 24.50% (5.52) respectively. It is therefore recommended that A. sativum(Gallic), S. aromatic (Clove) has showed larvacidal effects against Aedes mosquitoes and could be served as alternative form of botanical control against mosquitoes .
