Holi and the chemicals

Holi Holi which marks the harvest of Rabi crop and the arrival of springwas traditionally celebrated using natural coloured extracts from seasonal herbs. However, gradually these herbs were replaced by synthetic dyes ,some of which are toxic.This is because of the presence of mica,acids,alkalis, pieces of glass etc that are hazardous to huma Apart from inducing skin irritation and abrasion and these chemicals can go as far as impairing vision, causing cancer and respiratory problems.
Broadly there are three categories of colours available in the market:paste,dry powder and wet colours.All these could be hazardous.The hazard increases when these are mixed with oil .Oil helps the rogue chemicals to seep into the skin easily.
Holi pastes contain harmful chemicals such as Lead oxide (common in black colour), copper sulphate (found in green colour), aluminium bromide (in silver colour), prussian blue ( blue colour) and mercury sulphite ( a major component in red colour).These can cause renal failure, eye allergy, puffiness, temporary blindness, cancer etc.
Dry colours or gulaals have two components -a toxic colourant and a base which could be either asbestos or silica. Both these, especially asbestos, can cause health hazards even if exposure is limited.Gulaal has heavy metals called systemic toxins that can get deposited on kidneys, liver and bones .Presence of lead in Holi colours can lead to learning disorder,chromium to bronchial ailments,cadmium to fragile bones, nickel to dermatitis , mercury to nervous system disorder etc.
The wet colours have mostly gentian violet as a colour concentrate that can cause skin discolouration, dermatitis,irritation of mucous membrane etc.
Green
Dry Colour:
Dry and finely powder the leaves of Gulmohur (Delonix regia) tree for a green colour.
Crush the tender leaves of the Wheat plant to obtain a natural safe green Holi colour.
Wet colour:
Mix two teaspoons of haldi / Turmeric powder with double quantity of besan (gram flour). Haldi and besan are extremely healthy for our skin, and are also used widely as a ubtan while taking bath.
You can use the ordinary haldi or "kasturi" haldi which is very fragrant and has enhanced therapeutic effects. Besan can be substituted by atta, maida, rice flour, arra rot (ground nut) powder, fuller's earth (multani mitti) and even talcum powder.
Another Method
Flowers like Amaltas (Cassia fistula), Marigold / Gainda (Tagetus erecta), Yellow Chrysanthemums, Black Babul (Acacia arabica) yield different shades of yellow. Dry the petals of these flowers in shade and crush them to obtain a fine powder. Mix appropriate quantity of the powder with besan, etc. or use separately.
Dry the rind of the Bael fruit (Aegle marmelos) and grind to obtain a yellow powder.

Green
Dry Colour:
Use mehendi / henna powder, separately or mix with equal quantity of any suitable flour to attain a lovely green shade.
Make use only pure mehendi and not the one mixed with amla (meant to be applied to our hair) as this would be brown in colour. Dry mehendi will not leave colour on your face as it can be easily brushed off. Only when it is a paste (i.e. it is mixed in water) will it leave a slight colour on your face. Thus, it can be used as a pucca / fast colour.
Many people like smearing other person's hair with colours. How about doing it with mehendi powder and saving a trip to the parlour?

Celebrating a Safe and Eco-friendly Holi:

Judicious Use Of Water: In the current situation, when most cities in India are facing acute water scarcity, the wasteful use of water during Holi, is also being questioned. Thus recommend to play dry Holi with Gulal only.This will also save the risk of falling ill.
Avoid synthetic colours: Prefer preparing eco-friendly natural colours at home; haldi concoction for yellow, beetroot concoction for red, and methi or neem concoction for green. In any case, organic colors are now easily available in the market.
Smart use of Bonfire: Lighting of wooden pallets for the bonfire is a serious environmental issue. Would request you to lit one symbolic community bonfire, rather than burning individual bonfires across your locality as a way to reduce wood consumption. The other way is to lit bonfires by using waste material rather than wood.
Protect your eyes from attacks: Eyes are extremely vulnerable on Holi because of the use of harmful chemicals in colours these days. The chemicals can badly infect your eyes due to the toxic chemicals mixed with colours and can even cause blindness.
Play Safe: Don’t play with someone if he/she is not willing to play and do not let others to be rude with you. The best option would be to play with natural colours.
Preparations before Holi Celebration:
Make sure that you apply ample quantity of cream on your face before and after playing with colours. Cover up the body to the maximum with synthetic garments so that they do not soak much water.
Oil your hair well, it will make it easy for you to get rid of the colour stuck in the hairs. Also it will limit the effect of chemicals to hairs.
Keep your lips tightly locked so that colours do not enter your mouth. Also protect your face from any possible attack on face.
Try to avoid going outside of your premises in the peak hours of the festival. This way you can prevent yourself from being engaged with rough friends.
During travel, keep the window of your car tightly closed, even if you don’t have an AC car. Stay at a safe distance from the mob celebrating holi.
Take a bath with luke warm water after the Holi celebration is over. Avoid frequent washing of face and regular baths during the Holi celebration. It will ruin your skin with dryness.
Do not run and jump on wet floors as you may slip and pose the danger of bone fracture.
Avoid drinking of bhang and alcohol during festival. Do not drive when you are high on alcohol.
If you are asthmatic, take preventive doses in advance and keep S.O.S. inhalers [e.g. Astheline] handy. For such people, it is best to avoid playing Holi, if possible.
Keep anti-oxidants and other anti-allergic medicines ready for any accident or if you encounter any skin problem.
