Lotus leaf/honeysuckle/white chrysanthemum have similar and different effects, and brewing them separately can have a good effect.
Lavender has a soothing and calming effect. You can drink it when you are uneasy, have a bad sleep and are bored.
It is recommended to drink chrysanthemum and honeysuckle in summer to reduce fire, clear heat and detoxify.
About the cold, hehe, I haven't studied it. Taking medicine should help. Just kidding. I know I can drink rosemary and mint if I have a sore throat.
