1, mint leaves in the desert mean blessings, suggestions and tips. Desert people are always very happy with their guests' visits. The host usually goes out of the courtyard or greets them outside the tent, and after meeting them, he will hug and welcome them very warmly. When the guest comes in, the host and the guest sit on the floor. Before the conversation, guests are usually invited to drink three cups of mint tea to show their true feelings. According to the old proverb, serving three cups of tea means "blessing, suggestion and hint" respectively. The first cup wishes love as sweet as honey, the second cup remembers that life is as fragrant and bitter as mint, and the third cup reminds us that life is limited and death is ruthless.

2. The custom of Saharans drinking mint tea is accumulated in the struggle with the natural environment. The Sahara region has a large temperature difference between day and night, and it is also a place where "wear leather clothes early, wear yarn at noon and eat watermelon around the stove". People live in wild tents all the year round, and there is sand under a thin carpet or a sheepskin. The invasion of underground moisture often makes their back ache and their legs and feet weak. Tea can refresh, sugar can provide energy, and mint has the effect of relieving fever and dispelling cold. It can be seen that mint tea is the most suitable healthy drink for them.
