“中南海（蓝色风尚）” is crafted using high-quality Virginia tobacco from the United States and Brazil, combined with premium sun-cured tobacco from the Hubei Maryland tobacco leaf base established by the Beijing Cigarette Factory over many years. This unique blend employs a distinctive formula technology, creating a signature product style for the “中南海” brand. “中南海（蓝色风尚）” incorporates herbal extracts known for their strong expectorant, cough-relieving, and asthma-soothing properties, effectively reducing and suppressing harmful components of tobacco. The “蓝色风尚” product contains herbal essence, ensuring a smooth smoking experience without phlegm or cough. “中南海（蓝色风尚）” utilizes pure natural full hemp mesh paper, featuring a special ash-holding function that captures ash securely, allowing you to enjoy a fashionable and environmentally friendly experience without ash scattering. “中南海（蓝色风尚）” innovatively combines acetate fibers, green nano materials, and activated carbon into a three-component composite filter tip, successfully achieving targeted catalysis and selective adsorption of harmful substances in the smoke. This results in a reduction of harmful nitrosamines and polycyclic aromatic hydrocarbons by over 50% and 60%, respectively, significantly lowering the main carcinogenic components in cigarette smoke and meeting the low-harm standards set by the National Tobacco Monopoly Bureau, making it the first low-harm cigarette in China.
