Objective:To screen the hair colouring properties of hair colorants/ herbal hair colouring formulations.Materials and Methods:The dried aqueous herbal extracts of Gudhal leaves (Hibiscus rosa-sinensis), Jatamansi rhizome (Nardostachys jatamansi), Kuth roots (Saussurea lappa), Kattha (Acacia catechu), Amla dried fruit (Embelica officinalis), were prepared. Coffee powder (Coffea arabica) and Henna powder (Lowsonia inermis) were taken in the form of powder (# 40). Fourteen herbal hair colorants were prepared from these dried aqueous herbal extracts and powders. Activities of hair colorants were observed on sheep wool fibers. On the basis of the above observation six hair colorants were selected. These six formulations were taken for trials on human beings.Observation:The formulation coded HD-3 gave maximum colouring effect on sheep wool fibers as well as on human beings and percentage of acceptance among the volunteers were in the following order: HD- 3 > HD- 4 > HD-1 > HD-13 > HD-14 > HD-11.Results and Discussion:The remarkable results were obtained from five herbal hair colorants, viz., HD-1, HD- 3, HD- 4, HD-13 and HD-14 on sheep wool fibers and human beings. Formulation HD-3, having gudhal, jatamansi, kuth, kattha, amla, coffee and henna, was the maximum accepted formulation and suggested that these herbs in combination acts synergistically in hair colouring action. It also concluded that jatamansi, present in different hair colorants, was responsible to provide maximum blackening on hair

Flavonoids are broad-spectrum secondary metabolites with cosmetics, pharmaceutical, nutraceutical, and medicinal applications. They play a crucial role in life span shortening complications, including diabetes, CVS disorder, and cancer. They are the secondary metabolites essential natural products due to their anti-inflammatory, antioxidant, anticancer, anti-cholinesterase, disease combating, antimicrobial, hepatoprotective, neuroprotective, cardioprotective, antiallergic, and many more pharmacological activities causing substantial economic and social burdens. They have the ability to scavenge superoxide, hydroxyl, and lipid radicals. They are a group of polyphenolic compounds having 15 carbon skeleton consisting of two benzene rings with heterocyclic pyran ring, which are classified as anthocyanins, flavonols, isoflavonols, and flavanones, and present in vegetables, fruits, flowers, seeds, stems, and leaves.

Objective: Ziziphus jujuba, known as Ber (Hindi), is an indigenous herb found in India. Z. jujuba has been used to treat various diseases such as respiratory system diseases (asthma, cough, and laryngitis), gastrointestinal problems (constipation, colitis, and liver diseases), as well as cardiovascular and genitourinary system diseases. Seeds and fruit have been also reported to have central nervous system (CNS) depressant effect. Hence, in this study, neuropharmacological effects of leaves are studied which are not reported previously. Z. jujuba extract’s potential to depress the CNS and affect behavior was examined in this study, along with the phytochemicals that may be responsible for these effects. Methods: 400 mg/kg of the extract was administered intraperitoneally. As a benchmark, diazepam (2 mg/kg body weight i.p.) was used. ANOVA and Dunnett’s tests were used to evaluate the data. The results were all presented as Mean (SEM) values. p>0.05 was regarded as meaningful. Result: The outcome of the study demonstrated that ethanol extract of Z. jujuba (400 mg/kg i.p.) reduced locomotion, caused muscle relaxation, and had anti-anxiety effects. Conclusions: Ethanols extract of Z. jujuba leaves exhibits CNS depressant action and significant anxiolytic activity comparable to diazepam.
