For a concrete beam, the most popular cure is to use two flutes.
Another alternative is shown in the attachment. If the beam is concrete, then use the two wooden support as shown in the attach picture.

Vertical placement of bamboo flutes to neutralise a concrete beam
Another way of placing two bamboo flutes...please see illustration

If we use one of these alternatives to "neutralise" a beam, does this mean that afterwards one may sleep or sit under the beam without ill effects?

Dear Miriam,
Yes, one of these alternatives is meant to "neutralise" the beam.
Even under current situation (without a neutralsing agent); it is felt that one must be underneath the beam for more than 2hours per day per year to have any effects.
Warmest Regards,
Cecil
