Flos Rosae Chinensis — Rosa chinensis Jacq. (family Rosaceae), the dried flower or flower bud
Nature and flavour. Sweet, warm. Liver system.
The gentlest flower in this group, and the one whose classical indication is stated in emotional terms as well as gynaecological ones. It quickens the blood and regulates the menses, soothes the Liver and disperses depression, and is recorded for irregular or suppressed menstruation, for the distending chest and rib-side pain that the texts attribute to constrained Liver qi, and for the low spirits described in the same terms. It is also listed for swellings from knocks and falls, and it is a common ingredient in the compound formulas used for menstrual complaints in contemporary practice. The uses are recorded; the modern clinical evidence for them is limited and is not established.
性味归经。甘，温。归肝经。
本批中最温和的一味花类药，也是古典主治里既写妇科、又写情志的一味。功能活血调经、疏肝解郁；记载用于月经不调、经闭，古籍归因于肝气郁结的胸胁胀痛，以及同一描述下的情志不舒。亦载其治跌扑肿痛，并是当代调经复方中的常见成分。上述用途有文献记载，其现代临床证据有限，尚未被证实。
性味温和的活血药，孕期仍然要避开 —— 古籍对活血类花药在孕期是整类回避的。月经过多或经期延长者、有出血倾向者、以及合用抗凝或抗血小板药者均须谨慎。真正的风险不在药理而在来源：花店与庭院里的玫瑰不是这味药 —— 为观花而栽培的植株通常按观赏作物用药，所用杀虫剂与杀菌剂不允许出现在药用作物上，切花在切后亦可能另有处理。药材是通过药用供应链购买的规定部位，不是从花园里摘的一朵花。孕妇、不明原因的盆腔或经期出血者、以及情绪低落持续不退者，都应先去查明而不是自行处理 —— 出血与情绪低落各有需要查明的原因，一朵花对哪一样都不是答案。任何使用都须在合格执业者监督下进行；本页刻意不回答「该用多少」。
