Overview:

More than any other traditional or alternative medicine strategy, herbal medicines are closest to the conventional treatment method. Herbal remedies have been divided into four categories based on their origin, evolution, and contemporary forms of use, including indigenous herbal remedies; herbal remedies used in systems (AYUSH), modified herbal remedies, and imported goods with herbal medicine base. Herbal medications are dispensed or supplied mostly by pharmacists and are prescribed by doctors all over the world as adjuvant or adjuncts with contemporary drugs. Only the USA has laws that classify herbs as “dietary supplements” and have removed them from the medical prospect among developed nations. Herbal medicines have lot chemical constituents they are responsible for pharmacological effects in our body and that has been used many centuries. All over the world peoples accepting the herbal drugs because of the safety and efficacy. Nevertheless not have of guarantee of safety and efficacy of herbal medicines is to a big extent reason that of inadequate pharmacokinetic, pharmacodynamic and clinical data on the preponderance of herbal medicinal products.  The difficulty of regulating herbal pharmaceuticals is further complicated by the huge gap in meeting the legal standards for research on herbal drugs. For herbal practitioners, the criticism of herbal remedies from people all around the world has been enlightening. Even if clinical research were conducted at the time, there is still a long way to go before evidence-based medicine is at an international standard. Let us discuss the difficulties of doing clinical Trial on herbal drugs

A Requirement for Clinical Research on Herbal Drugs

All around the world, herbal products have grown to be a crucial and essential component of public healthcare. A number of studies on conventional and complementary medicine have revealed their pervasive use. However, clinical trials of these herbal products ought to be promoted in order to broaden their audience of acceptance. Use of single, dependable batches of formulations is advocated to demonstrate efficacy in clinical studies. Although many who use and believe in herbs do not need clinical studies, it is now necessary for their widespread acceptance and survival on the global market alongside modern pharmaceuticals.

The Difficulties of Conducting Clinical Research on Herbal Drugs:

There are a number of obstacles to research on herbal medicines that must be overcome. These include concerns including those pertaining to the financial, moral, product standardization, study design, and regulatory requirements before to registering an experimental new medication for the purpose of carrying out sizable phase III trials. The WHO developed operational guidelines that provide information on how to conduct clinical trials with herbal products; it has been argued that the inclusion criteria might be based either on current medical diagnosis or on the diagnostic of herbal medicine. In the case of herbal medicine and modern medicine, the understanding of the sickness and, consequently, the disease criteria can differ.

Choosing the inclusion and exclusion criteria for the assessment of herbal medicine are challenging in this situation. This problem has been resolved by using the “double classification approach” which classifies individuals after they have been initially principally diagnosed using current diagnostic standards. The traditional categorization is used to provide treatments, and the criteria for both classification systems are used to evaluate treatment outcomes.

Herbal medications have complicated treatments made up of a combination of active ingredients and instructions for administration.  Therefore, the patient’s willingness and drive to finish the course of therapy are key factors in the success of herbal treatment. However, by using blinding and randomization, these factors can be reduced. It is thought that randomization may do away with the practice of subjects being offered preferences for a particular therapy.

Blinding is a gold standard in randomized clinical trials (RCT) that removes bias and isolates placebo effects. RCTs are frequently double-blinded, which means neither the subject nor the researcher are aware of the treatment allocation. However, it is impossible to maintain double-blind in the case of herbal medicines since herbal treatment comprises a multifaceted therapeutic approach that includes counseling, listening, explaining, providing lifestyle and food guidance, as well as prescribing herbal drugs. Therefore, single blinding can be used in these interventions, where the researcher knows the treatment allocation but not the patient.

The choice of controls presents a further difficulty in the RCT of herbal medications. As comparison similarity is crucial if the trial is meant to give evidence of a specific impact of the herbal medication, controls are chosen so that they closely resemble the intervention group. Controls for elements including colour, odour, duration, frequency of intake, believability of the treatment to the patient, and the physical environment in which treatments are provided, should be standardized.

It is now understood that occupational standardization must continue. This is especially obvious in herbal product studies where the therapist actively participates. The protocol may make the practitioners feel uneasy since they want to offer the finest therapeutic care possible, which could lead to protocol violations. By offering treatment manuals outlining the particular steps to be taken, this therapist variability can be decreased.

Herbal medication has a unique approach and might not be standardized as a population-wide treatment.  Furthermore, the outcomes of trials may be influenced by the strong faith and confidence. It is necessary to conduct baseline evaluations of a variety of psychological variables, including mood and personality. The issue sample contamination is another matter of concern. The researchers should closely watch their trial participants to discover whether they look for herbal products outside of the established protocol. Above mentioned trial conduction practice to be supports in the herbal clinical research for overcome the issue arises during trial.
