The responses of young plants of diploid and tetraploid Matricaria chamomilla cultivars to abiotic stress were studied. The course of quantitative changes of main leaf secondary metabolites was evaluated within an interval from 6 h before to 54 h after spraying the leaf rosettes with aqueous CuCl2 solution. The content of herniarin in the treated plants rose approximately 3 times, simultaneousl...

Purpose Chamomile is a traditional herb known for its calming effects. We are conducting a long-term, randomized, placebo-substitution study of chamomile for the prevention of recurrent Generalized Anxiety Disorder (GAD) in individuals who have responded to initial, open-label chamomile therapy. We present preliminary results from the trial’s open label phase to offer initial evidence of safety...

Plant habit and production of secondary metabolites in chamomile plants depend on endogenous and exogenous factors that can be divided into two groups (FRANZ 1982): a) morpho-ontogenetic variability, b) genetic variability or genetic determinateness. The activity of these factors is reflected in biomass production, flower drug production, content and composition of essential oil and some other ...

The main objective of this study was to determine the effects of vermicompost and amino acids on the qualitative and quantitative yield of chamomile. The experiment was conducted during the growing season of 2010 at the Alborz Medical Research Center. The Treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the sprays of amino acids (budding stag, flowering stage, and bu...

background:  matricaria chamomilla is an ancient herbal drug widely consumed to sexual system improvement. the aim of this research was to study the effect of matricaria chamomilla hydroalcholic extract on the pituitary-testis axis and testes tissues of male rats. methods:  mature male rats were randomly assigned to two groups: the matricaria group (100 mg/kg of matricaria chamomilla extract vi...

Self-incompatible (SI) plants are able to form ideal mother lines for hybrid crossing in hermaphroditic plants, assuring fertilization from the desired father line. To find out suitable ways to maintain SI was the aim of this study. Among 220 plants of German chamomile (Matricaria recutita (L.) Rauschert) within six accessions SI-genotypes were selected. SI was determined as staying seedless in...
