The new heating and heat preservation device includes: at least one bag body, which has at least one holding space inside. The holding space is equipped with a plurality of iron powder, a plurality of carbon powder and a plurality of salts, each of which has a predetermined proportion.And at least one kind of plant, which is installed in the holding space. When the iron powder is oxidized, the plant generates heat energy and heats the plant, so as to place the bag on the skin of a human body, and use the heat energy to promote the absorption of the plant's properties or aroma through the skin to achieve the effect of relieving the affected part or muscle, while improving the blood circulation.本新型發熱保暖裝置，其包括：至少一袋體，其內部具有至少一容置空間，該容置空間內裝設有複數鐵粉、複數碳粉及複數鹽，且各該鐵粉、各該碳粉及各該鹽分別具有一預定比例。以及至少一種植物，該植物係裝設在該容置空間內，當各該鐵粉氧化時，產生熱能並加熱該植物，藉此將該袋體置於一人體的皮膚上，利用熱能促進經皮吸收植物的藥性或香氣來達到舒緩患部或肌肉的效果，同時增進血液循環。
