The main reason for launching this study is the lack of information that should be provided on the labels of tea packaging, sold in herbal shops and Albanian pharmacies. This paper aims to investigate and study the chemical profile using the GC-FID method of teas sold in Albanian pharmacies such as black tea, Althaea officinalis, Melissa officinalis, and Salvia rosmarinus. 4 different plants were taken for analysis: black tea was collected in China, while Althea officinalis, Melissa officinalis, and Salvia rosmarinus were collected in Albania. The plants were washed and their essential oils extracted: black tea and Althea officinalis were extracted by Clevenger apparatus. Melissa officinalis and Salvia rosmarinus were extracted by supercritical carbon dioxide (SC - CO2). For the presence of heavy metals such as Cd, Pb, Sn, and Hg, two methods were used: ultraviolet-visible (UV-VIS) spectrophotometers for plants after CO2 extraction, and inductively coupled plasma mass spectrometry (ICP-MS) was used for the essential oils obtained from the Clevenger apparatus. The data collected for these essential oils showed the high content of terpenes and monoterpenes in these essential oils as follows: 5.17% in black tea, 26.26% in Althaea officinalis, 40.4% in Salvia Rosmarinus, and 50% in Melissa officinalis.
