Simplified, chlorophyll is the pigment that makes plants green and is vital in said plants ability to absorb energy from light, also know as photosynthesis.
I'll spare you the science lesson and get to why this is important, why you might care.
There has been much hype surrounding green veggies in the recent years. What's not new is why much of the hype is actually legit. Vegetables are nature's gift to us - a tasty package of many of the nutrients we need to survive. In addition, fresh, green veggies and herbs are full of chlorophyll. Chlorophyll is said to aid the body in cleansing and detoxifying its cells [of which our bodies are made up of]. A clean, healthy cell has a better chance of optimally utilizing nutrients.
Of course, the best way to get chlorophyll is through fresh vegetables, but in the winter green is scarce. I've found taking chlorophyll in liquid form to be a nice stand-in rather than paying the high price for fresh greens flown in from various continents. In combination with the frozen veggies tucked in my freezer, chlorophyll helps nourish my body throughout the long winter months.
I want to be very clear that I'm not suggesting chlorophyll as the magic cure to prevent illness and I'm certainly not saying replace fresh green vegetables with chlorophyll. Illness happens even to the healthiest eaters, especially when said eaters have children in school. Green vegetables and herbs contain so many more nutrients in addition to chlorophyll and it would be a foolish substitution for the green stuff direct from the ground. I am suggesting that green, in liquid form, can aid a body in ridding the stuff that needs to go and strengthening the systems that could use it in months that come up empty in green.
As always, please research for yourself before giving chlorophyll a try and if you have specific health concerns or illness, consult a well-trained physician of natural medicine or your doctor prior to use.
