Can water boiled with leucaena root, lotus root and reed root cure nosebleeds?

Nosebleed is called epistaxis (nosebleed) in Chinese medicine. Radix Bupleurum Chinense, Radix et Rhizoma Gastrodiae and Radix Rehmanniae are Chinese herbal medicines and can be used together to treat epistaxis caused by exogenous fever and blood-heat syndromes. However, the active ingredients in boiled water may be limited, so it is recommended to take them in decoction as prescribed by the doctor.
Radix Imperata Cylindrica has the efficacy of cooling blood, stopping bleeding, clearing heat and inducing diuresis. It is used in treating hematemesis, epistaxis, blood in urine, thirst and fever, jaundice due to dampness-heat, edema with scanty urination, and heat drenching (burning and stinging pain during urination, accompanied by frequent urination and urgency, and discomfort of pulling in the abdomen) with astringent pain.
Lotus root has the efficacy of astringency to stop bleeding (using drugs with astringent effect to treat bleeding disorders) and resolving blood stasis. It is used in treating vomiting of blood, hemoptysis, epistaxis, urinary blood, and metrorrhagia (excessive menstrual flow or dribbling).
Rehmannia glutinosa has the efficacy of clearing heat and fire, generating body fluid to quench thirst, removing vexation, relieving vomiting and inducing diuresis. It is used in treating fever and thirst, lung-heat cough, lung carbuncle and pus spitting, stomach-heat vomiting and retching, and hot shower and astringent pain. It is not recommended for people with cold spleen and stomach.
Commiphora root, lotus root and rehmannia root used together can be used in treating epistaxis caused by exogenous fever, blood heat, etc. However, boiled water may not be enough to treat epistaxis. However, boiling the medicines in water may not achieve the effect of treating the disease. Epistaxis should be treated with medication under the guidance of a physician and should not be self-medicated to avoid adverse consequences.
