Phenylalanine, an amino acid, is a "building block" of protein. Phenylalanine is a component of food sources and also derived through supplementation. In current treatment, phenylalanine is prescribed as anti-depressant agent. The present study reviewed the possible antidepressant potential of phenylalanine. We reviewed data using the major databases, namely, Web of Science, SciFinder, Google Scholar, and PubMed. This manuscript provides a brief overview of the role of phenylalanine in depressive disorders. Phenylalanine possesses anti-depressant potential. Significant anti-depressant activities have been studied both in-vitro and in-vivo models. Based on current data, phenylalanine could be recommended as a potential candidate for clinical anti-depressant trials. Phenylalanine hydroxylase (PAH) deficiency results in intolerance to the dietetic consumption of the phenylalanine and a variety of syndromes such as deep and permanent logical disability, impaired cognitive development.

The research examines the differences between populations and medical applications of allergic rhinitis patients who received all three treatments to determine the use of different drugs. Methods: The inventory for patients diagnosed with allergic rhinitis (International Disease Classification). The Chi-square test and Tukey test were performed for the region of interest to check the disparity between these three treatments (a significant difference still exists). The interview rate for women with allergic rhinitis is higher than for men regardless of whether it is treatment with traditional Chinese medicine, Western or combined traditionalChinese and Western medicine.Traditional Chinese medicine includes medical measures with maximum hours per person, the daily cost per hour of medicines and minimum overall hourly expenditure. Western medicine, by comparison, costs the lowest daily drug per hour, and the highest total drug costs per hour per person. Between traditional Chinese and western medicine, the total cost per capita of integrated traditional Chinese and Western Medicine as well as drug costs per capita and the total cost per capita. Although only 6.82% of allergic rhinitis patients opt for combinedtraditional Chinese medicines and western medicine, their rate of receipt is higher each year.

Diarrhea is a common gastrointestinal problem characterized by loose watery stool and mild to severe dehydration. Annually, about 1.7-5 billion new cases of diarrhea were reported. In developing countries, it is more common, where young kids have diarrhea approximately three times/year. In 2013, 1.26 million deaths occurred due to diarrhea, whereas in 1990, the figure was slightly higher (2.58 million). In 2012, diarrhea was the second most common reason of death (11%, n = 0.76 million) in children less than 5 years. Although various synthetic drugs are being prescribed as standard therapy for diarrhea, they have side effects. It is possible to prescribe the herbal medicine for diarrhea, which is safe and effective. In this study, medicinal plants discussed are proven to be scientifically active in diarrheal diseases. This study reviews about current medicinal plants used in the treatment of diarrhea. The use of medicinal plants for diarrhea results in improvement of the symptom. Moreover, studies on large scale are needed to characterize the beneficial role of medicinal plants in the treatment of diarrhea.
