Надеюсь, что приведенная в таблице информация может оказаться полезной как для фитотерапевтов и исследователей в области создания противораковых препаратов, так и для обычных людей, так как нужно знать, что нас с вами окружает, и не уподобляться нашим предкам, которые пробовали всё на вкус – «методом проб и ошибок». Тем более, ни в коем случае нельзя полагаться на мнение торгашей и прочей «мышкующей» братии.
По сравнению с некоторыми нашими достаточно цитотоксическими растениями (например, с экстрактами почек тополя - ТС 50 = 0.0062% или Ветренницы алтайской - ТС 50 = 0.0051) можно считать, что экстракты зелёного чая обладают средней цитотоксичностью. Но в отличие от приведенных выше растений они используются во всём мире, и хорошо изучены. Это подтверждается многочисленными исследованиями, результаты которых суммированы в приведенных ниже таблицах.

Приведенные данные свидетельствуют о том, что экстракты зелёного чая обладают способностью блокировать неконтролируемое деление клеток в человеческом организме и у животных (противораковая активност) и положительно влиять на сердечно - сосудистую систему..Наряду с этим его экстракты способны достаточно мягко тормозить развитие бактериальной микрофлоры и существенно снижать концентрацию различных вирусных объектов. Эти обстоятельства подтверждены в наших экспериментах на модельных бактериальных и вирусных культурах. Поэтому нам просто грешно пренебрегать зелёным чаем даже, если он горький на вкус и кому-то может не нравиться запах этого чая. Ведь именно этот пищевой продукт при постоянном применении может служить в качестве профилактического и даже лечебного средства от заболеваний, ответственных за наш ранний уход из жизни.
Вот и автор этого профилактического эссе утром выпил две чашки крепкого чая (две чайные ложечки сухого зелёного чая «с горкой» на две чашки кипятка) и в обед (добавив дополнительно ещё одну ложечку сухой заварки и 2-3 чашки кипятка) повторит эту процедуру. Так продолжается уже несколько лет, и я не собираюсь останавливаться - мне это нравится. Надеюсь, что читатели не принимают меня за торговца или рекламиста, выполняющего заказ.
А вам, уважаемые читатели, особенно в моём возрасте после всего прочитанного, неужели по утрам только кофе? Пишите - будем вместе радоваться жизни. Каждый по своему!
