Brief summary

This proposed study aims to investigate the association between a mixture of herb and how it could affect both body weight and depression in people who are on prescribed antidepressants. The mixture of herbs include red chili powder, black pepper, ginger, and turmeric . With the aid of DEXA scanning and SCID “a test to evaluate depression” this study will aim to examine if consuming the herbs mixture affects body weight or depression. It became a fact that people who are on prescribed antidepressants tend to gain weight. There are some studies in the past that attempted to create a remedy for the problem. None of them have proposed that herbs can be used together with antidepressants to reduce weight gain. Flyers and posters will be distributed to announce and recruit volunteers between 18 and 54 years old. Pages on on Facebook can be created to announce the trial. Clinical Trials Connect Database will be used as well to recruit with an in-built screening system. Women who are pregnant, people who are highly dependent on medical care, have a cognitive impairment, or intellectual disability will not be included in this study. However, our main target is people who are on antidepressants and suffering from depression. The duration of the study will be three months. During this time, the participants will be asked to use a mixture of four herb. The four herbs are Black pepper, Red chilli powder, Ginger, and Turmeric. The ability of these herbs to help with weight problems will be examined by using three groups of people. The first is the control group, which comprises of overweight but non-depressed subjects who take only the herb mixture. The second group comprises the depressed subjects who take only antidepressants with placebo. The third group "the main group" comprises of subjects who take the antidepressants together with the herb. Changes in body (weight/body-fat) and depression will be assessed using three main tests that will be repeated monthly; DEXA scanning to see changes in body fat, the Scale to test body weight, SCID to test depression, and Blood samples to see if there is an improvement in the blood inflammatory markers (C-reactive protein CRP).
