Yes, hawthorn has many functions, such as helping to increase appetite and cancer, as well as removing blood stasis, stopping bleeding, preventing heatstroke and refreshing. Lemon contains a lot of vitamins, so drinking more is also beneficial. Soaking in water together has the effects of clearing away heat and invigorating the stomach, quenching thirst and promoting fluid production, and has a certain effect of reducing blood fat.
My very best wishes to your health
