This invention discloses the application of a traditional Chinese medicine composition in combination with miplatin in the preparation of a breast cancer treatment drug. The composition contains at least: verbena, polygonum cuspidatum, red peony root, peony bark, and atractylodes macrocephala (fried), preferably: honeysuckle 10-20 parts, forsythia 5-15 parts, peppermint 1-11 parts, burdock fruit 5-14 parts, mulberry leaf 4-14 parts, chrysanthemum 4-14 parts, golden lotus 7-18 parts, holly 5-15 parts, verbena 10-20 parts, polygonum cuspidatum 5-15 parts, red peony root 6-17 parts, peony bark 4-14 parts, solidarium 6-17 parts, licorice 1-11 parts, and atractylodes macrocephala (fried) 5-14 parts. The mass ratio of the extract powder obtained from the raw materials to miplatin is 1000-5000:1. The formulation of this invention is based on the core idea of ​​synergistic enhancement, toxicity reduction and efficacy improvement. It is the first time that the five herbs Verbena officinalis, Polygonum cuspidatum, Paeonia lactiflora, Paeonia suffruticosa, and Atractylodes macrocephala (fried) have been shown to work synergistically. The combination of traditional Chinese medicine and miplatin significantly improves the therapeutic effect.

This invention discloses a method for controlling Canadian goldenrod, belonging to the field of biological control technology. The method includes: physical tilling combined with chemical spraying during the seedling stage; tilling followed by application of biological herbicides during the vegetative growth stage; spraying flower bud inhibitors to suppress seed formation during the flowering stage; and physical removal during the seed maturation stage. This invention employs a phased, multi-pronged, synergistic comprehensive control strategy, targeting the biological characteristics of Canadian goldenrod at different growth stages, and combining chemical, biological, and physical methods to achieve highly efficient, long-lasting, and environmentally friendly control effects. This significantly reduces problems such as herbicide resistance, high recurrence rates, and environmental pollution caused by single-method control.
