The purpose of the current study was to examine the effect of hydroalcoholic extract of Psidium guajava plant on bone marrow cells in rats and it will be extended to humans. Guava plant leaves were collected from Chabahar region in Sistan and Baluchistan province and dried. 40 adult male rats were assigned to one control group and three experimental groups (subjects that were administeredhydroalcoholic extract of P. guajava leaves with respective doses of 3000 mg/kg, 4000 mg/kg, or 5000 mg/kg, for 3 months, once daily). Following the intervention period, blood was taken from the heart and bone marrow was taken from the femur. Several parameters such as cell blood count, hemoglobin, and hematocrit, were examined in the blood sample. Also, in the bone marrow sample, a relative count was performed on five hundred bone marrow cells and the ratio of myeloid to erythroid was determined in both control and experimental groups. The results of this study indicated that the hydroalcoholic extract somewhat increased white blood cells and red blood cells, but no significant change was observed. The result of the study revealed the positive effects of guava leaf extract may be due to flavonoids, quercetin and triterpenes, which strong antioxidants that can prevent damage are caused by free radicals destroying cells. This study shows that guava leaf extract can have a positive effect on hematological parameters, as well as the lack of mutagenicity and cytotoxicity in high doses of this plant extract rather reflects its safe use in traditional medicine. Therefore, it is recommended that guava leaf extract be considered as a complementary and alternative treatment for many diseases, including the treatment of anemia.

Most of the plants are essential due to their medicinal properties and have contributed to the origin and evolution of many traditional herbal therapies. Rheum is also one of the famous and known medicinal plants of Kashmir Himalaya. It ranges from an altitude of 1700-5500 m. Its Roots are long and stout. The stem is erect, hollow, sulcate, glabrous, or strigose. It is native to Asia-Temperate to Asia-Tropical, from China to India, Nepal, and Pakistan. In India, its found in Himachal Pradesh, Jammu and Kashmir, and Uttar Pradesh. Rhubarb is the English name of the genus Rheum (family Polygonaceae). Emodi, Webbianum and Spiciforme are three species of Rheum found in Kashmir Himalaya. Rheum species are well-known medicinal plant and is found on high altitudes. Its leaves and stalks are taken as food and cooked as vegetables. It’s used as medicine and is generally proven more effective against certain ailments like antibacterial, anticancerous, anti-inflammatory, rheumatoid diseases, stomachache, and intestinal problems. It is also used for the treatment of indigestion, abdominal disorders, boils, wounds and flatulence. But Rheum has become endangered due to exploitation. Active compounds like aloe-emodin, rhein, emodin, chrysaphanol and physicion are found in this plant which is anti Cancerian agents. High molecular diversity is also observed in all the three species of Rheum.

Systemic bacterial and fungal infections in recent years due to the increasing number of debilitating diseases immune system such as AIDS, blood malignancies, overdose, corticosteroid drugs, and broad-spectrum antibiotics has been raised. There is a prevalence of acute and subsequent candida infections with drug-resistance properties such as fluconazole. Due to the prevalence and spread of fungal and bacterial diseases, the effort to find treatments has increased more than before. The use of plant compounds for the therapy of fungal and bacterial diseases is effective due to their unique biocompatible and bioavailable. The trend toward new antifungal and antibacterial agents being introduced to the market remains small, while resistance to many antibiotics is emerging, especially in patients receiving long-term treatment. Considering the enormous antimicrobial potentials of natural compounds isolated from plants and endophytes and screening of new antibiotics for various pharmaceutical applications as an alternative source remains largely unknown. Endophytes and medicinal plant species have main primary and secondary metabolites suitable to hindrance or inactivation of pathogens. Recently, various studies about the antibacterial and antifungal activities of these metabolites have been reported. For this purpose, in this review, antibacterial and antifungal activities of endophytes of Pestalotiopsis genus and medicinal plant species of Zingiber and Hydnora genera have been discussed according to recent studies.
